1. A healthcare provider is caring for a group of individuals who are not immune to Varicella. The healthcare provider should prepare to administer the Varicella vaccine at this time to which of the following individuals?
- A. 24-year-old woman in the third trimester of pregnancy
- B. 12-year-old child who has a severe allergy to neomycin
- C. 2-month-old infant who has no health problems
- D. 32-year-old man who has essential hypertension
Correct answer: D
Rationale: The correct answer is the 32-year-old man with essential hypertension. Individuals not immune to Varicella should receive the vaccine if they did not get two doses earlier. Essential hypertension is not a contraindication for the Varicella vaccine. Administering the vaccine to pregnant women, individuals with severe neomycin allergies, or infants is contraindicated. Pregnant women should not receive the Varicella vaccine due to the potential risk to the fetus. Severe neomycin allergies are a contraindication because neomycin is present in the vaccine. Infants under 12 months of age are generally not vaccinated against Varicella unless there are specific circumstances or recommendations.
2. What is the pharmacological action of metformin?
- A. Blocks stimulation of beta1 and beta2.
- B. Blocks vasoconstriction and aldosterone.
- C. Acts at many levels in the CNS to produce an anxiolytic effect.
- D. Decreases hepatic glucose production.
Correct answer: D
Rationale: The correct answer is D: Decreases hepatic glucose production. Metformin's primary pharmacological action is to decrease hepatic glucose production, leading to lower blood sugar levels and improved insulin sensitivity in the liver. Choices A, B, and C are incorrect because metformin does not block stimulation of beta1 and beta2 receptors, vasoconstriction, aldosterone, or act in the CNS to produce an anxiolytic effect. Therefore, these options are not reflective of metformin's mechanism of action.
3. A client has a new prescription for Cyanocobalamin (Vitamin B12) injections. Which of the following client statements indicates an understanding of the teaching?
- A. I will need to take this medication for the rest of my life.
- B. I will stop taking the medication when my symptoms improve.
- C. I should take this medication with food.
- D. I will need to avoid green, leafy vegetables while taking this medication.
Correct answer: A
Rationale: The correct answer is A. Clients with pernicious anemia or other causes of vitamin B12 deficiency may need to take cyanocobalamin for life to prevent deficiency. It is a lifelong treatment in many cases to maintain adequate B12 levels. Choice B is incorrect because stopping the medication when symptoms improve may lead to a relapse of the deficiency. Choice C is incorrect as cyanocobalamin injections are usually administered on an empty stomach. Choice D is incorrect as there is no need to avoid green, leafy vegetables while taking cyanocobalamin; in fact, these vegetables are good dietary sources of vitamin B12.
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 client has been prescribed an ACE Inhibitor for hypertension. Which of the following instructions should be included by the healthcare provider?
- A. Avoid salt substitutes.
- B. Take this medication at bedtime.
- C. Avoid foods high in potassium.
- D. Limit your fluid intake.
Correct answer: A
Rationale: The correct answer is to 'Avoid salt substitutes.' ACE Inhibitors can increase potassium levels, so clients should avoid salt substitutes that contain potassium to prevent hyperkalemia, which is a potential side effect of ACE Inhibitors. Choice B 'Take this medication at bedtime' is incorrect as ACE Inhibitors are usually taken in the morning to avoid nocturnal diuresis. Choice C 'Avoid foods high in potassium' is incorrect because although ACE Inhibitors can increase potassium levels, clients are generally encouraged to consume potassium-rich foods in moderation unless contraindicated. Choice D 'Limit your fluid intake' is also incorrect as ACE Inhibitors do not typically require fluid restrictions unless specified by a healthcare provider for other reasons.
