RN HESI Exit Exam Capstone

Correct Answer: D

Rationale: The correct answer is D: 'Use sunscreen to prevent photosensitivity.' Methotrexate increases photosensitivity, so clients should be advised to use sunscreen to protect their skin from sun exposure. Choice A is incorrect because methotrexate is usually taken with food to reduce gastrointestinal side effects. Choice B may be important but is not specific to methotrexate therapy. Choice C is also important, but the primary reason for folic acid supplementation with methotrexate is to reduce the risk of certain side effects like anemia rather than preventing anemia itself.

Correct Answer: D

Rationale: During a tonic-clonic seizure, the nurse should loosen restrictive clothing to prevent injury and ease the client to the floor to ensure safety. Placing any object, such as a tongue depressor, in the client's mouth is contraindicated as it may cause harm. Restraint should not be used as it can lead to injury. Beginning CPR is not indicated during a seizure unless the client experiences cardiac arrest, which is a rare complication of seizures.

Correct Answer: D

Rationale: The correct answer is D: Reduce gastric acid secretion. Proton pump inhibitors (PPIs) work by reducing gastric acid secretion, which helps prevent further irritation of the gastric mucosa and allows ulcers to heal. While promoting healing of the gastric mucosa (Choice A) is an indirect outcome of reducing gastric acid secretion, the primary mechanism of PPIs is to lower acid levels. Choice B, neutralizing the effects of stomach acid, is typically associated with antacids, not PPIs. Inhibiting the growth of Helicobacter pylori (Choice C) is usually achieved with antibiotics, not PPIs.

Correct Answer: B

Rationale: The correct teaching for a client prescribed hydrochlorothiazide is to increase fluid intake to prevent dehydration. Hydrochlorothiazide is a diuretic that can lead to fluid loss and electrolyte imbalances, so adequate fluid intake is crucial. Choice A is incorrect because hydrochlorothiazide is typically taken in the morning to avoid nighttime urination. Choice C is incorrect as potassium-rich foods should not be avoided but monitored, as hydrochlorothiazide can cause potassium loss. Choice D is incorrect as potassium levels should be monitored regularly, but not necessarily weekly, unless indicated by the healthcare provider.

Correct Answer: D

Rationale: The correct intervention for a 5-week-old infant with hypertrophic pyloric stenosis presenting with projectile vomiting is to maintain intravenous fluid therapy. This is essential to maintain hydration before surgery. Instructing the mother to give sugar water only (Choice A) is inadequate and does not address the need for proper hydration. Offering oral rehydration every 2 hours (Choice B) may not be effective in cases of severe vomiting and could lead to further fluid loss. Providing Pedialyte feedings via nasogastric tube (Choice C) is an option, but in severe cases, intravenous fluid therapy is more effective in ensuring hydration and electrolyte balance.
