Nursing Elites

1. In which of the following cases is dehydration more likely to occur?

• A. A 50-year-old woman who is a bodybuilder
• B. A 50-year-old man who is morbidly obese
• C. A 10-year-old child who is thin
• D. A 30-year-old with multiple sclerosis

Correct answer: B

Rationale: Dehydration is more likely to occur in a 50-year-old man who is morbidly obese due to the increased risk of conditions like diabetes and heart disease that can lead to fluid imbalances. Being morbidly obese can also strain the body's systems, increasing the need for water. The other choices are less likely to experience dehydration as a primary concern. While being a bodybuilder may require strict hydration practices, dehydration is more prevalent in individuals with conditions like obesity.

2. In which patient would the manifestation of a headache be a sign of a serious underlying disorder?

• A. A 55-year-old man with new onset of headaches that are worse at night and reported mood swings according to his family
• B. A 30-year-old woman with a unilateral throbbing headache with photophobia and nausea
• C. A 60-year-old man with his head feeling full and throbbing and muscle aching around his neck and shoulders
• D. A 40-year-old woman who experiences food cravings, gets irritable, and then develops a pulsatile-like headache on the right side of her head

Correct answer: A

Rationale: The correct answer is A. New onset headaches in older adults, especially if worse at night, may indicate a serious condition like a brain tumor. Choice B describes symptoms commonly seen in migraines. Choice C describes tension-type headaches. Choice D describes symptoms of a menstrual migraine which is not typically associated with a serious underlying disorder.

3. Which of the following statements describes an active cellular membrane exchange process?

• A. Sodium moving out of cells and potassium moving into cells
• B. The movement of water from an area of low solute concentration to an area of high solute concentration
• C. The movement of insulin using a protein to travel across the cell membrane
• D. Oxygen moving across the pulmonary capillaries to an area of high carbon dioxide

Correct answer: A

Rationale: The correct answer is A. In active transport, energy is expended to move substances against their concentration gradient. Sodium moving out of cells and potassium moving into cells is an example of active transport because it requires energy to pump these ions across the cell membrane against their concentration gradients. Choices B, C, and D describe passive processes where substances move along their concentration gradients without the input of energy.

4. A patient is being educated about sildenafil (Viagra). Which of the following statements by the patient indicates that further teaching is necessary?

• A. I can take this medication with nitroglycerin.
• B. This medication can cause an erection lasting more than 4 hours.
• C. I should not take this medication if I am taking medications containing nitrates.
• D. This medication is safe to take with any over-the-counter medication.

Correct answer: A

Rationale: The correct answer is A because sildenafil should not be taken with medications containing nitrates, such as nitroglycerin, due to the risk of severe hypotension. Choice B is incorrect because priapism (prolonged erection) is a serious side effect but does not require immediate intervention like severe hypotension. Choice C is incorrect as it correctly identifies a contraindication for sildenafil use. Choice D is incorrect because not all over-the-counter medications are safe to take with sildenafil, and interactions can occur.

5. What is a critical point the nurse should include in patient education for a patient prescribed tamoxifen (Nolvadex)?

• A. Tamoxifen may increase the risk of venous thromboembolism.
• B. Tamoxifen may decrease the risk of osteoporosis.
• C. Tamoxifen may cause hot flashes and other menopausal symptoms.
• D. Tamoxifen may cause weight gain and fluid retention.

Correct answer: A

Rationale: The critical point the nurse should include in patient education for a patient prescribed tamoxifen is that it may increase the risk of venous thromboembolism. This is crucial information because tamoxifen is known to promote blood clot formation, and patients need to be aware of the signs and symptoms of blood clots to seek prompt medical attention. Choices B, C, and D are incorrect as tamoxifen is not associated with decreasing the risk of osteoporosis, causing hot flashes and other menopausal symptoms, or directly causing weight gain and fluid retention.
