Question 1 of 5
An 85-year-old male has been losing mobility and gaining weight over the last two months. The patient also has the heater running in his house 24 hours a day, even on warm days. Which of the following tests is most likely to be performed?
Correct Answer: C
Rationale: The symptoms of weight gain and poor temperature tolerance in an elderly male suggest a potential thyroid dysfunction. Thyroid function tests are crucial in differentiating between hyperthyroidism, hypothyroidism, and a euthyroid state. These tests involve measuring the serum levels of thyroid hormones T3 and T4, also known as thyroxine, to evaluate thyroid function accurately. A complete blood count (
Choice
A) would not directly address the symptoms presented. An electrocardiogram (
Choice
B) assesses heart activity and would not be the primary test for these symptoms. A CT scan (
Choice
D) provides detailed images of internal organs and structures, which would not be the initial investigation for the described symptoms.
Question 2 of 5
A mother has recently been informed that her child has Down syndrome. You will be assigned to care for the child at shift change. Which of the following characteristics is not associated with Down syndrome?
Correct Answer: C
Rationale: Individuals with Down syndrome commonly have certain physical characteristics, such as a simian crease (single transverse palmar crease), brachycephaly (shortened front-to-back skull dimension), and hypotonicity (low muscle tone). Oily skin is not a characteristic associated with Down syndrome; instead, individuals with Down syndrome often have dry skin.
Therefore, oily skin is the correct answer in this context.
Question 3 of 5
A child weighing 30 kg arrives at the clinic with diffuse itching as the result of an allergic reaction to an insect bite. Diphenhydramine (Benadryl) 25 mg 3 times a day is prescribed. The correct pediatric dose is 5 mg/kg/day. Which of the following best describes the prescribed drug dose?
Correct Answer: B
Rationale: The correct pediatric dose of diphenhydramine is 5 mg/kg/day. This child weighs 30 kg, so the calculated dose would be 5 mg/kg x 30 kg = 150 mg/day. Since the prescription is for 25 mg 3 times a day, the total daily dose is 25 mg x 3 = 75 mg/day, which is lower than the calculated dose of 150 mg/day.
Therefore, the prescribed dose of 25 mg 3 times a day is too low for this child. The dose should be adjusted to meet the correct dosage of 150 mg/day, which would be 50 mg 3 times a day. It is important not to titrate the dosage based on symptoms without consulting a physician, as this can lead to inappropriate medication administration.
Question 4 of 5
A thirty-five-year-old male has been an insulin-dependent diabetic for five years and now is unable to urinate. Which of the following would you most likely suspect?
Correct Answer: C
Rationale: In this case, the correct answer is autonomic neuropathy. Autonomic neuropathy affects the autonomic nerves, which control various bodily functions including the bladder. In diabetes, it can lead to bladder paralysis, resulting in symptoms like urgency to urinate and difficulty initiating urination. Atherosclerosis (choice
A) is a condition involving the hardening and narrowing of arteries, not directly related to the inability to urinate in this context. Diabetic nephropathy (choice
B) primarily affects the kidneys, leading to kidney damage, but does not typically cause urinary retention. Somatic neuropathy (choice
D) involves damage to sensory nerves, not the autonomic nerves responsible for bladder control, making it less likely to be the cause of the urinary issue described in the question.
Question 5 of 5
A teen patient is admitted to the hospital by his physician who suspects a diagnosis of acute glomerulonephritis. Which of the following findings is consistent with this diagnosis? Select one that doesn't apply.
Correct Answer: D
Rationale: The correct answer is 'Generalized edema.' Acute glomerulonephritis typically presents with periorbital edema, not generalized edema. Findings in acute glomerulonephritis include dark, smoky, or tea-colored urine (hematuria) due to red blood cells in the urine, elevated blood pressure, and proteinuria. The urine specific gravity may be high due to decreased urine output, but a urine output of 350 ml in 24 hours is extremely low and suggestive of renal impairment. Generalized edema is more commonly associated with nephrotic syndrome, where there is significant proteinuria leading to hypoalbuminemia and subsequent fluid retention in tissues. In acute glomerulonephritis, the edema is usually limited to the face and lower extremities, not generalized.
