Answers and Rationale

1. Answer: A

The parathyroid glands regulate the calcium level in the blood. In hyperparathyroidism, the serum calcium level will be elevated. Parathyroid hormone levels may be high or normal but not low. The body will lower the level of vitamin D in an attempt to lower calcium. Urine calcium may be elevated, with calcium spilling over from elevated serum levels. This may cause renal stones.

2. Answer: D

A patient with Addison's disease requires normal dietary sodium to prevent excess fluid loss. Adequate caloric intake is recommended with a diet high in protein and complex carbohydrates, including grains.

3. Answer: C

A post-operative diabetic patient who is unable to eat is likely to be suffering from hypoglycemia. Confusion and shakiness are common symptoms. An anesthesia reaction would not occur on the second post-operative day. Hyperglycemia and ketoacidosis do not cause confusion and shakiness.

4. Answer: A

Bowel perforation is the most serious complication of fiberoptic colonoscopy. Important signs include progressive abdominal pain, fever, chills, and tachycardia, which indicate advancing peritonitis. Viral gastroenteritis and colon cancer do not cause these symptoms. Diverticulitis may cause pain, fever, and chills, but is far less serious than perforation and peritonitis.

5. Answer: A, B, and C

Prothrombin time, partial thromboplastin time, and platelet count are all included in coagulation studies. The hemoglobin level, though important information prior to an invasive procedure like liver biopsy, does not assess coagulation.

6. Answer: B

Hepatitis A is the only type that is transmitted by the fecal-oral route through contaminated food. Hepatitis B, C, and D are transmitted through infected bodily fluids.

7. Answer: A

Hepatitis C is a viral infection transmitted through bodily fluids, such as blood, causing inflammation of the liver. Patients with hepatitis C may not donate blood for transfusion due to the high risk of infection in the recipient. Cholecystitis (gall bladder disease), diverticulosis, and history of Crohn's disease do not preclude blood donation.

8. Answer: A

Naproxen sodium is a nonsteroidal anti-inflammatory drug that can cause inflammation of the upper GI tract. For this reason, it is contraindicated in a patient with gastritis. Calcium carbonate is used as an antacid for the relief of indigestion and is not contraindicated. Clarithromycin is an antibacterial often used for the treatment of Helicobacter pylori in gastritis. Furosemide is a loop diuretic and is contraindicated in a patient with gastritis.

9. Answer: D

Cholecystitis, inflammation of the gallbladder, is most commonly caused by the presence of gallstones, which may block bile (necessary for fat absorption) from entering the intestines. Patients should decrease dietary fat by limiting foods like fatty meats, fried foods, and creamy desserts to avoid irritation of the gallbladder.

10. Answer: D

Patients with pulmonary edema experience air hunger, anxiety, and agitation. Respiration is fast and shallow and heart rate increases. Stridor is noisy breathing caused by laryngeal swelling or spasm and is not associated with pulmonary edema.

11. Answer: C

An automatic internal cardioverter-defibrillator delivers an electric shock to the heart to terminate episodes of ventricular tachycardia and ventricular fibrillation. This is necessary in a patient with significant ventricular symptoms, such as tachycardia resulting in syncope. A patient with myocardial infarction that resolved with no permanent cardiac damage would not be a candidate. A patient recovering well from coronary bypass would not need the device. Atrial tachycardia is less serious and is treated conservatively with medication and cardioversion as a last resort.

12. Answer: B

The implanted pacemaker will interfere with the magnetic fields of the MRI scanner and may be deactivated by them. Shellfish/iodine allergy is not a contraindication because the contrast used in MRI scanning is not iodine-based. Open MRI scanners and anti-anxiety medications are available for patients with claustrophobia. Psychiatric medication is not a contraindication to MRI scanning.

13. Answer: B

Typical symptoms of pulmonary embolism include chest pain, shortness of breath, and severe anxiety. The physician should be notified immediately. A patient with pulmonary embolism will not be sleepy or have a cough with crackles on exam. A patient with fever, chills and loss of appetite may be developing pneumonia.

14. Answer: C

A rapidly enlarging abdominal aortic aneurysm is at significant risk of rupture and should be resected as soon as possible. No other appropriate treatment options currently exist.

15. Answer: D

A platelet count of 25,000/microliter is severely thrombocytopenic and should prompt the initiation of bleeding precautions, including monitoring urine and stool for evidence of bleeding. Monitoring for fever and requiring protective clothing are indicated to prevent infection if white blood cells are decreased. Transfusion of red cells is indicated for severe anemia.

16. Answer: B

Increased pressure caused by bleeding or swelling within the skull can damage delicate brain tissue and may become life threatening. Repeated vomiting can be an early sign of pressure as the vomit center within the medulla is stimulated. The anterior fontanel is closed in a 4-year-old child. Evidence of sleepiness at 10 PM is normal for a four year old. The average 4-year-old child cannot read yet, so this too is normal.

17. Answer: A

Koplik's spots are small blue-white spots visible on the oral mucosa and are characteristic of measles infection. The body rash typically begins on the face and travels downward. High fever is often present. "Tear drop on a rose petal" refers to the lesions found in varicella (chicken pox).

18. Answer: C

Petechiae on the soft palate are characteristic of rubella infection. Choices A, B, and D are characteristic of scarlet fever, a result of group A Streptococcus infection.

19. Answer: B

This child weighs 30 kg, and the pediatric dose of diphenhydramine is 5 mg/kg/day (5 X 30 = 150/day). Therefore, the correct dose is 150 mg/day. Divided into 3 doses per day, the child should receive 50 mg 3 times a day rather than 25 mg 3 times a day. Dosage should not be titrated based on symptoms without consulting a physician.

20. Answer: D

Normally, the testes descend by one year of age. In young infants, it is common for the testes to retract into the inguinal canal when the environment is cold or the cremasteric reflex is stimulated. Exam should be done in a warm room with warm hands. It is most likely that both testes are present and will descend by a year. If not, a full assessment will determine the appropriate treatment.

21. Answer: C

The staging of Wilm's tumor is confirmed at surgery as follows: Stage I, the tumor is limited to the kidney and completely resected; stage II, the tumor extends beyond the kidney but is completely resected; stage III, residual nonhematogenous tumor is confined to the abdomen; stage IV, hematogenous metastasis has occurred with spread beyond the abdomen; and stage V, bilateral renal involvement is present at diagnosis.

22. Answer: A, B, and C

Acute glomerulonephritis is characterized by high urine specific gravity related to oliguria as well as dark "tea colored" urine caused by large amounts of red blood cells. There is periorbital edema, but generalized edema is seen in nephrotic syndrome, not acute glomerulonephritis.

23. Answer: B

Acute glomerulonephritis is most commonly caused by the immune response to a prior upper respiratory infection with group A Streptococcus. Glomerular inflammation occurs about 10-14 days after the infection, resulting in scant, dark urine and retention of body fluid. Periorbital edema and hypertension are common signs at diagnosis.

24. Answer: C

A hydrocele is a collection of fluid in the scrotum that results from a patent tunica vaginalis. Illumination of the scrotum with a pocket light demonstrates the clear fluid. In most cases the fluid reabsorbs within the first few months of life and no treatment is necessary. Massaging the area or placing the infant in a supine position would have no effect. Surgery is not indicated.

25. Answer: A

Patients with peripheral vascular disease often sustain nerve damage as a result of inadequate tissue perfusion. Fluid overload is not characteristic of PVD. There is nothing to indicate psychiatric disturbance in the patient. Skin changes in PVD are secondary to decreased tissue perfusion rather than primary inflammation.

26. Answer: A

Family history of heart disease is an inherited risk factor that is not subject to life style change. Having a first degree relative with heart disease has been shown to significantly increase risk. Overweight and smoking are risk factors that are subject to life style change and can reduce risk significantly. Advancing age increases risk of atherosclerosis but is not a hereditary factor.

27. Answer: A, C, and D

Claudication describes the pain experienced by a patient with peripheral vascular disease when oxygen demand in the leg muscles exceeds the oxygen supply. This most often occurs during activity when demand increases in muscle tissue. The tissue becomes hypoxic, causing cramping, weakness, and discomfort.

28. Answer: C

Patients with peripheral vascular disease should avoid crossing the legs because this can impede blood flow. Walking barefoot is not advised, as foot protection is important to avoid trauma that may lead to serious infection. Heating pads can cause injury, which can also increase the risk of infection. Skin lesions at risk for infection should be examined and treated by a physician.

29. Answer: C

Raynaud's disease is most common in young women and is frequently associated with rheumatologic disorders, such as lupus and rheumatoid arthritis.

30. Answer: B

In a hospitalized patient on prolonged bed rest, he most likely cause of sudden onset shortness of breath and chest pain is pulmonary embolism. Pregnancy and prolonged inactivity both increase the risk of clot formation in the deep veins of the legs. These clots can then break loose and travel to the lungs. Myocardial infarction and atherosclerosis are unlikely in a 27-year-old woman, as is congestive heart failure due to fluid overload. There is no reason to suspect an anxiety disorder in this patient. Though anxiety is a possible cause of her symptoms, the seriousness of pulmonary embolism demands that it be considered first.

31. Answer: B

Cerebral hemorrhage is a significant risk when treating a stroke victim with thrombolytic therapy intended to dissolve a suspected clot. Success of the treatment demands that it be instituted as soon as possible, often before the cause of stroke has been determined. Air embolus is not a concern. Thrombolytic therapy does not lead to expansion of the clot, but to resolution, which is the intended effect.

32. Answer: A

In torticollis, the sternocleidomastoid muscle is contracted, limiting range of motion of the neck and causing the chin to point to the opposing side. In craniosynostosis one of the cranial sutures, often the sagittal, closes prematurely, causing the head to grow in an abnormal shape. Plagiocephaly refers to the flattening of one side of the head, caused by the infant being placed supine in the same position over time. Hydrocephalus is caused by a build-up of cerebrospinal fluid in the brain resulting in large head size.

33. Answer: C

Osgood-Schlatter disease occurs in adolescents in rapid growth phase when the infrapatellar ligament of the quadriceps muscle pulls on the tibial tubercle, causing pain and swelling in the inferior aspect of the knee. Osgood-Schlatter disease is commonly caused by activities that require repeated use of the quadriceps, including track and soccer. Swimming is not a likely cause. The condition is usually self-limited, responding to ice, rest, and analgesics. Continued participation will worsen the condition and the symptoms.

34. Answer: D

A check for scoliosis, a lateral deviation of the spine, is an important part of the routine adolescent exam. It is assessed by having the teen bend at the waist with arms dangling, while observing for lateral curvature and uneven rib level. Scoliosis is more common in female adolescents. Choices A, B, and C are not part of the routine adolescent exam.

35. Answer: C

The profile of a parent at risk of abusive behavior includes a tendency to blame the child or others for the injury sustained. These parents also have a high incidence of low self-esteem, unemployment, unstable financial situation, and single status.

36. Answer: 3

Nonsteroidal anti-inflammatory drugs are important first line treatment for juvenile idiopathic arthritis (formerly known as juvenile rheumatoid arthritis). NSAIDs require 3-4 weeks for the therapeutic anti-inflammatory effects to be realized. Half of children with the disorder recover without joint deformity, and about a third will continue with symptoms into adulthood. Physical activity is an integral part of therapy.

37. Answer: B

Antibiotics must be started after the blood culture is drawn, as they may interfere with the identification of the causative organism. The blood count will reveal the presence of infection but does not help identify an organism or guide antibiotic treatment. Parental presence is important for the adjustment of the child but not for the administration of medication.

38. Answer: A

The child's refusal to walk, combined with swelling of the limb is suspicious for fracture. Toddlers will often continue to walk on a muscle that is bruised or strained. The radius is found in the lower arm and is not relevant to this question. Toddlers rarely feign injury to be carried, and swelling indicates a physical injury.

39. Answer: A, B, D

Delayed developmental milestones are characteristic of cerebral palsy, so regular screening and intervention is essential. Because of injury to upper motor neurons, children may have ocular and speech difficulties. Parent support groups help families to share and cope. Physical therapy and other interventions can minimize the extent of the delay in developmental milestones.

40. Answer: A

The recessive Duchenne's gene is located on one of the two X chromosomes of a female carrier. If her son receives the X bearing the gene he will be affected. Thus, there is a 50% chance of a son being affected. Daughters are not affected, but 50% are carriers because they inherit one copy of the defective gene from the mother. The other X chromosome comes from the father, who cannot be a carrier.
