- A. The client must lie still throughout the test.
- B. The client will have an EKG after the test.

Commercially available analogs of 1,25-dihydroxyvitamin D3 (calcitriol) are:
- A. Doxercalciferol (Hectoral)
- B. Paricalcitol (Zemplar)
- C. All of the above
- D. None of the above
Correct Answer: C
Rationale: Rationale:
1. Both Doxercalciferol (Hectoral) and Paricalcitol (Zemplar) are synthetic analogs of 1,25-dihydroxyvitamin D3.
2. Doxercalciferol is converted to calcitriol in the body.
3. Paricalcitol is a selective vitamin D receptor activator.
Summary:
A: Doxercalciferol is correct as it is a synthetic analog of calcitriol.
B: Paricalcitol is correct as it is also a synthetic analog of calcitriol.
C: Correct as both A and B are true.
D: Incorrect as both A and B are commercially available analogs of calcitriol.
Which of the following antihyperlipidemic drugs would be relatively contraindicated in this patient?
- A. Cholestyramine
- B. Niacin
- C. Ezetimibe
- D. Lovastatin
Correct Answer: B
Rationale: The correct answer is B: Niacin. Niacin can cause hepatotoxicity and exacerbate liver conditions, which would be a concern in this patient. Cholestyramine (A) works in the intestines, Ezetimibe (C) inhibits cholesterol absorption, and Lovastatin (D) inhibits cholesterol synthesis in the liver, none of which are contraindicated in liver conditions.
Gemfibrozil (Lopid) increases concentrations of HDL cholesterol more than clofibrate (Atromid-S). This consideration is:
- A. TRUE
- B. FALSE
- C. All
- D. None
Correct Answer: A
Rationale: The correct answer is A: TRUE. Gemfibrozil (Lopid) is known to be more effective at increasing HDL cholesterol levels compared to clofibrate (Atromid-S). This is supported by clinical studies showing a greater impact on HDL concentrations with gemfibrozil. Choice B is incorrect as it contradicts the established evidence. Choices C and D are also incorrect as they do not accurately reflect the comparative efficacy between Gemfibrozil and clofibrate in increasing HDL cholesterol levels.
Which of the following statements is correct for zolpidem?
- A. Causes minor effects on sleep patterns
- B. The risk of development of tolerance and dependence is less than with the use of hypnotic benzodiazepines
- C. Has minimal muscle relaxing and anticonvulsant effects
- D. All of the above
Correct Answer: D
Rationale: Step 1: Zolpidem is a sedative-hypnotic medication used for treating insomnia by enhancing the effects of GABA in the brain.
Step 2: Zolpidem causes significant effects on sleep patterns, not minor ones, making option A incorrect.
Step 3: Zolpidem has a lower risk of tolerance and dependence compared to benzodiazepines, making option B correct.
Step 4: Zolpidem primarily acts as a sedative and does not have significant muscle relaxing or anticonvulsant effects, making option C incorrect.
Step 5: Combining the above points, option D is correct as it encompasses the accurate statements about zolpidem.
Beta-adrenoceptor antagonists:
- A. Increase cardiac tissue cyclic adenosine monophosphate (cAMP)
- B. Competitively antagonize the beta receptor-mediated effects of adrenaline and noradrenaline
- C. Non-competitively antagonize several of the actions of thyroxine
- D. Decrease peripheral vascular resistance
Correct Answer: B
Rationale: Beta blockers competitively block catecholamines (B) and reduce renin (E); they decrease cAMP (A), do not affect thyroxine (C), and increase peripheral resistance (D).
