1. The healthcare professional is preparing to administer atenolol (Tenormin) to a client with angina. Which vital sign would cause the healthcare professional to question administering this drug?

A. Respirations 12 breaths per minute
B. Pulse 52 beats per minute
C. Blood pressure 134/72
D. Oxygen saturation 95%

Correct answer: B

Rationale: Atenolol is a beta-blocker medication that can lower heart rate. A pulse of 52 beats per minute is relatively low and administering atenolol could further decrease the heart rate, potentially leading to bradycardia. Monitoring the pulse rate and holding the medication if the pulse is below the prescribed parameters is crucial to prevent adverse effects such as bradycardia and hypotension.

2. A client has a new prescription for a combination of oral NRTIs (abacavir, lamivudine, and zidovudine) for the treatment of HIV. Which of the following statements should the nurse include in teaching the client?

A. These medications work by blocking HIV entry into cells.
B. These medications work by weakening the cell wall of the HIV virus.
C. These medications work by inhibiting enzymes to prevent HIV replication.
D. These medications work by preventing protein synthesis within the HIV cell.

Correct answer: C

Rationale: The NRTI antiretroviral medications this client is prescribed work by inhibiting the enzyme reverse transcriptase, thus preventing HIV replication. By inhibiting this crucial enzyme, the drug interferes with the virus's ability to replicate and spread in the body. Choice A is incorrect because NRTIs do not block HIV entry into cells. Choice B is incorrect as NRTIs do not weaken the cell wall of the virus. Choice D is incorrect as NRTIs do not prevent protein synthesis within the HIV cell.

3. What is a common side effect of Albuterol?

A. Paradoxical Bronchospasm
B. Diarrhea
C. Seizures
D. Vision Loss

Correct answer: A

Rationale: A common side effect of Albuterol is paradoxical bronchospasm, a condition where the airways become more constricted instead of relaxing. This can be a serious adverse reaction to the medication. Choices B, C, and D are incorrect as they are not commonly associated with Albuterol use. Diarrhea and seizures are not typically reported side effects of Albuterol, and vision loss is not a recognized side effect of this medication.

4. A female client with tobacco use disorder is being educated by a nurse about Nicotine replacement therapy. Which of the following statements by the client shows understanding of the teaching?

A. I should avoid eating right before I chew a piece of nicotine gum.
B. I will need to stop using the nicotine gum after 1 year.
C. I know that nicotine gum is a safe alternative to smoking if I become pregnant.
D. I must chew the nicotine gum quickly for about 15 minutes.

Correct answer: A

Rationale: The correct answer is A. The client should avoid eating or drinking 15 minutes prior to and while chewing the nicotine gum. Choice B is incorrect because there is no specified timeline for stopping nicotine gum use. Choice C is incorrect because nicotine gum is not recommended during pregnancy. Choice D is incorrect as the client should chew the nicotine gum slowly for about 30 minutes, not quickly for 15 minutes.

5. A healthcare professional is preparing to administer vancomycin 1 g by intermittent IV bolus. Available is vancomycin 1 g in 100 mL of dextrose 5% in water (D5W) to infuse over 45 min. The drop factor of the manual IV tubing is 10 gtt/mL. How many gtt/min should the healthcare professional adjust the manual IV infusion to deliver?

A. 22 gtt/min
B. 24 gtt/min
C. 20 gtt/min
D. 18 gtt/min

Correct answer: A

Rationale: To determine the flow rate in drops per minute (gtt/min), you can use the formula: (Volume in mL x Drop factor) / Time in minutes = Flow rate in gtt/min. In this case, it would be (100 mL x 10 gtt/mL) / 45 min = 22 gtt/min. Therefore, the healthcare professional should adjust the manual IV infusion to deliver 22 gtt/min. Choice B, 24 gtt/min, is incorrect as it results from a miscalculation. Choices C and D, 20 gtt/min and 18 gtt/min respectively, are also incorrect calculations based on the given parameters.
