1. Which of the following is a factor that leads to increased risk for dehydration in the elderly?

Correct answer: C

Rationale: The correct answer is C: Decline in kidney function. As people age, their kidneys may not work as effectively in conserving water and concentrating urine, leading to a higher risk of dehydration. Choice A is incorrect because more insensible losses do not directly relate to an increased risk of dehydration in the elderly. Choice B, an increase in muscle mass, is not a factor that leads to dehydration. Choice D, a decrease in fat, is also not a direct factor contributing to dehydration in the elderly.

2. Why is the administration of benzene hexachloride (Lindane) for the treatment of scabies applied in small quantities?

Correct answer: A

Rationale: The rationale for instructing the patient to apply benzene hexachloride (Lindane) in small quantities for scabies treatment is that excessive applications can lead to central nervous system toxicity. Lindane is a neurotoxin, and overuse or incorrect application can result in adverse effects on the central nervous system, such as seizures, dizziness, and even death. Choices B, C, and D are incorrect because they do not reflect the specific toxic effects associated with Lindane, which primarily affects the central nervous system rather than causing skin irritation, gastrointestinal symptoms, or metabolic issues.

3. A patient is prescribed tadalafil (Cialis) for erectile dysfunction. What condition would contraindicate the use of this medication?

Correct answer: B

Rationale: The correct answer is B: 'Use of nitrates.' Tadalafil (Cialis) is contraindicated in patients using nitrates due to the risk of severe hypotension. Nitrates and tadalafil both cause vasodilation, leading to a synergistic effect that can result in a dangerous drop in blood pressure. Choices A, C, and D are incorrect because a history of hypertension, the use of antihypertensive medications, and a history of peptic ulcer disease are not direct contraindications for tadalafil use.

4. A patient is prescribed sildenafil (Viagra) for erectile dysfunction. What critical contraindication should the nurse review with the patient?

Correct answer: A

Rationale: The correct answer is A: Use of nitrates. Sildenafil (Viagra) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates and sildenafil both cause vasodilation, which can lead to a dangerous drop in blood pressure. Choice B (Use of antihypertensive medications) is incorrect because antihypertensive medications are not a critical contraindication for sildenafil use. Choice C (History of hypertension) is incorrect as it is not a contraindication for sildenafil; in fact, sildenafil is sometimes used in patients with hypertension. Choice D (History of peptic ulcer disease) is also incorrect as it is not a critical contraindication for sildenafil use.

5. Which of the following women are at highest risk for the development of endometrial cancer?

Correct answer: B

Rationale: The correct answer is B. Obesity and irregular menstrual cycles, including periods of amenorrhea and infrequent periods, are significant risk factors for the development of endometrial cancer. Choice A is less likely as postmenopausal status reduces the risk. Choice C is not directly associated with a high risk of endometrial cancer. Choice D, smoking, is more strongly linked to other types of cancers like lung cancer rather than endometrial cancer.
