1. Which of the following clients should refrain from therapy with the thiazide diuretic hydrochlorothiazide?

• A. a client with renal impairment
• B. a client with hypertension
• C. a client with diabetes mellitus, type II
• D. a client with renal calculi (kidney stones)

Correct answer: C

Rationale: The correct answer is a client with diabetes mellitus, type II. Thiazide diuretics like hydrochlorothiazide can cause metabolic abnormalities, including elevated blood glucose levels. This increase is linked to diuretic-induced potassium deficiency, which reduces insulin secretion, leading to higher plasma glucose levels. Thiazides are commonly used in clients with renal impairment and hypertension. Moreover, thiazides decrease calcium excretion, reducing the risk of renal calculi, so it is not contraindicated for clients with kidney stones. Therefore, clients with diabetes mellitus, type II should avoid therapy with hydrochlorothiazide due to the potential adverse effects on blood glucose levels.

2. Before administering Theodur to a 10-year-old being treated for asthma, the nurse should check the:

• A. Urinary output
• B. Blood pressure
• C. Pulse
• D. Temperature

Correct answer: C

Rationale: The correct answer is to check the pulse. Theodur is a bronchodilator used in asthma treatment, and one of the side effects is tachycardia (increased heart rate). Therefore, it is essential to assess the pulse rate before administering Theodur to monitor for any potential tachycardia. Checking urinary output (Choice A), blood pressure (Choice B), and temperature (Choice D) are not directly related to the immediate side effects of bronchodilators like Theodur in this context, making them unnecessary assessments.

3. Which laboratory test would be the least effective in diagnosing a myocardial infarction?

• A. AST
• B. Troponin
• C. CK-MB
• D. Myoglobin

Correct answer: A

Rationale: AST, choice A, would be the least effective in diagnosing a myocardial infarction as it is not specific for this condition. Troponin, CK-MB, and myoglobin (choices B, C, and D) are more specific markers for myocardial infarction. Troponin is considered the gold standard due to its cardiac specificity. CK-MB is also specific to the heart, and its isoenzyme levels elevate post-heart damage. Myoglobin, although elevated in myocardial infarction, is not as specific as troponin and CK-MB and can also increase in conditions like burns and muscle trauma. Therefore, AST is the least effective choice for diagnosing a myocardial infarction.

4. In the United States, several definitions of death are currently being used. The definition that uses apnea testing and pupillary responses to light is termed:

• A. whole brain death.
• B. heart-lung death.
• C. circulatory death.
• D. higher brain death.

Correct answer: A

Rationale: The correct answer is 'whole brain death.' Most protocols for determining whole brain death require two separate clinical examinations, including the induction of painful stimuli, pupillary responses to light, oculovestibular testing, and apnea testing. This comprehensive approach ensures that all functions of the brain, including the brainstem, are evaluated to confirm the absence of brain function. Choices B and D are incorrect as they do not reflect the specific tests required for determining whole brain death. Choice C, 'circulatory death,' does not involve the evaluation of brain function and is not a current definition of death in the United States.

5. The licensed practical nurse is observing a graduate nurse as she assesses the central venous pressure. Which observation would indicate that the graduate needs further teaching?

• A. The graduate places the client in a supine position to read the manometer.
• B. The graduate turns the stop-cock to the off position from the IV fluid to the client.
• C. The graduate instructs the client to perform the Valsalva maneuver during the CVP reading.
• D. The graduate notes the level at the top of the meniscus.

Correct answer: C

Rationale: The correct answer is C because the client should breathe normally during a central venous pressure monitor reading. Placing the client in a supine position (Choice A) is correct if the client can tolerate it. Turning the stop-cock off (Choice B) and noting the level at the top of the meniscus (Choice D) are also correct actions during CVP monitoring. Instructing the client to perform the Valsalva maneuver is incorrect as it can artificially alter the CVP reading, indicating a need for further teaching.
