Nursing Elites

1. When teaching a young woman about the use of hormonal contraceptives, a nurse should emphasize that these drugs are most effective when taken:

• A. Immediately after sexual intercourse.
• B. At the same time each day.
• C. Before going to bed at night.
• D. On an empty stomach.

Correct answer: B

Rationale: The correct answer is B: 'At the same time each day.' Hormonal contraceptives should be taken consistently at the same time each day to maintain stable hormone levels, which is crucial for their effectiveness. Taking them at random times can increase the risk of contraceptive failure. Choices A, C, and D are incorrect because taking hormonal contraceptives immediately after sexual intercourse, before going to bed at night, or on an empty stomach does not align with the recommended usage instructions for these drugs.

2. A male patient is being treated with sildenafil (Viagra) for erectile dysfunction. What condition would contraindicate the use of this medication?

• A. Peptic ulcer disease
• B. History of myocardial infarction
• C. Recent use of antihypertensive medications
• D. Use of nitrates

Correct answer: D

Rationale: The correct answer is D: Use of nitrates. Sildenafil (Viagra) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates and sildenafil both cause vasodilation, and the combination can lead to a dangerous drop in blood pressure. Choice A, peptic ulcer disease, is not a contraindication for sildenafil use. Choice B, a history of myocardial infarction, is not a contraindication unless the patient is also taking nitrates. Choice C, recent use of antihypertensive medications, is not a contraindication but requires caution as the combination can lead to additive effects lowering blood pressure.

3. Which of the following patients are at higher risk for developing oral cancer?

• A. A female who has taken oral contraceptives for the last 4 years
• B. Both an adult male with a history of alcoholism and a middle-aged male who smokes a pipe
• C. An adult female who eats spicy foods regularly
• D. An older adult female who chews gum frequently

Correct answer: B

Rationale: The correct answer is 'Both an adult male with a history of alcoholism and a middle-aged male who smokes a pipe.' Alcohol consumption and tobacco use, such as smoking a pipe, are well-known risk factors for developing oral cancer. These two factors significantly increase the likelihood of developing oral cancer compared to the other choices. Taking oral contraceptives, eating spicy foods regularly, and chewing gum frequently are not established risk factors for oral cancer, making them less likely to lead to the development of this type of cancer.

4. When reviewing the purpose/action of neurotransmitters as they interact with different receptors, the nursing instructor gives an example using acetylcholine. When acetylcholine is released at the sinoatrial node in the right atrium of the heart, it is:

• A. positively charged.
• B. inhibitory.
• C. overstimulated.
• D. dormant.

Correct answer: B

Rationale: Acetylcholine acts as an inhibitory neurotransmitter at the sinoatrial node. It slows down the heart rate by decreasing the firing rate of the sinoatrial node, which serves as the heart's natural pacemaker. Neurotransmitters do not have a charge, so choice A is incorrect. Choice C is wrong as overstimulation is not a characteristic of acetylcholine at the sinoatrial node. Choice D is also incorrect because acetylcholine actively influences heart rate regulation when released at the sinoatrial node.

5. A male patient is receiving testosterone therapy for hypogonadism. What adverse effect should the nurse monitor for during this therapy?

• A. Increased risk of cardiovascular events
• B. Increased risk of liver dysfunction
• C. Increased risk of prostate cancer
• D. Increased risk of bone fractures

Correct answer: A

Rationale: The correct answer is A: Increased risk of cardiovascular events. Testosterone therapy for hypogonadism is associated with an increased risk of cardiovascular events, such as myocardial infarction and stroke. Monitoring for signs and symptoms of cardiovascular issues is crucial during testosterone therapy. Choices B, C, and D are incorrect because testosterone therapy is not typically associated with an increased risk of liver dysfunction, prostate cancer, or bone fractures.
