1. A 15-year-old high school wrestler has been taking diuretics to lose weight to compete in a lower weight class. Which of the following medical tests is most likely to be given?
- A. Lab values of Potassium and Sodium
- B. Lab values of Glucose and Hemoglobin
- C. ECG
- D. CT scan
Correct answer: Lab values of Potassium and Sodium
Rationale: Diuretics can disrupt the sodium and potassium balance, potentially leading to cardiac complications. Monitoring the lab values of potassium and sodium is crucial to assess electrolyte imbalances due to diuretic use. Testing glucose and hemoglobin levels is not directly related to diuretic use in this context. An ECG would be indicated if there were signs or symptoms of cardiac abnormalities, but it is not the primary test to monitor the effects of diuretics. A CT scan is not typically used to assess electrolyte imbalances caused by diuretics.
2. The physician has ordered sodium warfarin (Coumadin) for the client with thrombophlebitis. The order should be entered to administer the medication at:
- A. 0900
- B. 1200
- C. 1700
- D. 2100
Correct answer: 1700
Rationale: Sodium warfarin is typically administered in the late afternoon, around 1700 hours. This timing allows for accurate bleeding times to be drawn in the morning. Administering it at 0900 (choice A) would not align with this schedule and may affect the monitoring of bleeding times. Choice B (1200) is midday, which is not the recommended time for sodium warfarin administration. Choice D (2100) is in the evening, which is also not ideal. Therefore, the correct time for administering sodium warfarin is 1700 (choice C).
3. A nurse in the healthcare provider's office is checking the Babinski reflex in a 3-month-old infant. The nurse determines that the infant's response is normal if which finding is noted?
- A. The fingers curl tightly, and the toes curl forward.
- B. The toes flare, and the big toe is dorsiflexed.
- C. There is extension of the extremities on the side to which the head is turned, with flexion on the opposite side.
- D. The infant turns to the side that is touched.
Correct answer: The toes flare, and the big toe is dorsiflexed.
Rationale: To elicit the Babinski reflex, the nurse strokes the lateral sole of the foot from the heel to across the base of the toes. In the expected response, the toes flare, and the big toe dorsiflexes. The Babinski reflex disappears at 12 months of age. Turning to the side that is touched is the expected response when the rooting reflex is elicited. Tight curling of the fingers and forward curling of the toes is the expected response when the grasp reflex (palmar and plantar) is elicited. Extension of the extremities on the side to which the head is turned with flexion on the opposite side is the expected response when the tonic neck reflex is elicited.
4. Which of the following enzymes is indicative of pancreatitis?
- A. alkaline phosphatase
- B. acid phosphatase
- C. creatine phosphokinase
- D. amylase
Correct answer: D: amylase
Rationale: Amylase is elevated in conditions of pancreatic inflammation, such as pancreatitis. Pancreatitis is characterized by the inflammation of the pancreas, leading to the leakage of amylase into the bloodstream. Elevated levels of amylase are a key diagnostic marker for pancreatitis. Alkaline phosphatase is associated with liver and bone conditions, not pancreatitis. Acid phosphatase is more related to prostate health and is not specific to pancreatitis. Creatine phosphokinase is found in tissues like muscle and brain, and elevated levels are seen in conditions like muscle injury or heart attack, not pancreatitis.
5. A test that can correctly identify those who do not have a given disease is:
- A. specific.
- B. sensitive.
- C. negative culture.
- D. marginal finding.
Correct answer: specific.
Rationale: The correct answer is 'specific.' A specific test correctly identifies individuals who do not have a particular disease. In this case, since the lab culture report is negative for the suspected infection, it means the test is good at ruling out the disease. 'Sensitive' (choice B) would be incorrect as sensitivity refers to a test's ability to correctly identify individuals who do have the disease. 'Negative culture' (choice C) is incorrect as it describes the result rather than the test's characteristic. 'Marginal finding' (choice D) is unrelated to the concept of correctly identifying individuals without the disease.
