Nursing Elites

1. A male patient with erectile dysfunction has asked for a prescription for sildenafil (Viagra). Before giving this medication, the nurse should assess for which of the following conditions?

• A. History of peptic ulcer disease
• B. Use of nitrates
• C. Recent history of a stroke
• D. History of hypertension

Correct answer: B

Rationale: The correct answer is B: Use of nitrates. Sildenafil should not be used by patients taking nitrates due to the risk of severe hypotension. Nitrates can potentiate the hypotensive effects of sildenafil, leading to a significant drop in blood pressure. Assessing for the use of nitrates is crucial to avoid this potentially dangerous interaction. Choices A, C, and D are incorrect because they are not specifically contraindications for the use of sildenafil. While a history of hypertension should be considered, it is not as critical as the use of nitrates when prescribing sildenafil.

2. A patient with a history of hypertension presents with a severe headache, confusion, and visual disturbances. His blood pressure is 220/120 mm Hg. Which of the following is the most likely diagnosis?

• A. Migraine
• B. Cluster headache
• C. Hypertensive emergency
• D. Tension headache

Correct answer: C

Rationale: A patient with a history of hypertension presenting with a severe headache, confusion, and visual disturbances, along with a blood pressure of 220/120 mm Hg, likely has a hypertensive emergency. In this situation, the severely elevated blood pressure can lead to end-organ damage, causing symptoms such as headache and confusion. Migraine and tension headaches are not associated with such high blood pressure levels. Cluster headaches typically do not present with visual disturbances and confusion in the setting of severe hypertension.

3. After a 27-year-old woman with epilepsy had a generalized seizure, she feels tired and falls asleep. This is:

• A. an ominous sign.
• B. normal and termed the postictal period.
• C. a reflection of an underlying brain tumor.
• D. only worrisome if there are focal neurologic deficits after.

Correct answer: B

Rationale: The correct answer is B: normal and termed the postictal period. The postictal period is a common phase following a seizure where the individual may experience fatigue, confusion, or sleepiness. It is a normal part of the seizure event and does not necessarily indicate a serious issue. Choice A is incorrect because feeling tired and falling asleep after a seizure is not an ominous sign but rather a typical postictal symptom. Choice C is incorrect as there is no indication in the scenario provided that links the symptoms to an underlying brain tumor. Choice D is incorrect because the absence of focal neurologic deficits does not make the postictal period worrisome.

4. A woman is complaining that she feels like the room is spinning even though she is not moving. Which of the following is characteristic of benign positional vertigo?

• A. It usually occurs with a headache.
• B. Pupillary changes are common.
• C. It is usually triggered when the patient bends forward.
• D. Nystagmus continues even when the eyes fixate on an object.

Correct answer: C

Rationale: The correct answer is C: 'It is usually triggered when the patient bends forward.' Benign positional vertigo is often triggered by changes in head position, such as bending forward. Choices A, B, and D are incorrect. A is incorrect because benign positional vertigo is not typically associated with headaches. B is incorrect because pupillary changes are not a common feature of benign positional vertigo. D is incorrect because nystagmus in benign positional vertigo usually stops when the eyes fixate on an object.

5. Which of the following statements indicates more teaching is needed regarding secondary lymph organs? ________is/are a secondary lymph organ.

• A. The spleen
• B. Peyer's patches
• C. Adenoids
• D. The liver

Correct answer: D

Rationale: The correct answer is D, 'The liver.' The liver is not a secondary lymph organ. Secondary lymph organs are primarily involved in the immune response, such as the spleen, Peyer's patches, and adenoids. The spleen filters blood and is essential for immune function. Peyer's patches are located in the small intestine and help protect against pathogens. Adenoids are located in the throat and play a role in immune defense. Therefore, the liver is the incorrect choice as it is not part of the secondary lymph organ system.
