HESI RN
HESI Nutrition Exam
1. Discharge instructions for a client taking alprazolam (Xanax) should include which of the following?
- A. Sedative hypnotics are effective analgesics
- B. Sudden cessation of alprazolam (Xanax) can cause rebound insomnia and nightmares
- C. Caffeine beverages can increase the effect of sedative hypnotics
- D. Avoidance of excessive exercise and high temperature is recommended
Correct answer: B
Rationale: The correct answer is B. Alprazolam should not be stopped abruptly as it can cause rebound insomnia and nightmares; gradual tapering is necessary. Choice A is incorrect as sedative hypnotics are not primarily used as analgesics. Choice C is incorrect as caffeine can decrease the effects of sedative hypnotics rather than increase them. Choice D is incorrect as there is no specific recommendation to avoid excessive exercise or high temperature related to alprazolam use.
2. A patient asks the nurse about taking calcium supplements to avoid hypocalcemia. The nurse will suggest that the patient follow which instruction?
- A. Take a calcium and vitamin D combination supplement.
- B. Take calcium along with phosphorus to improve absorption.
- C. Take calcium with antacids to reduce stomach upset.
- D. Use aspirin instead of acetaminophen when taking calcium.
Correct answer: A
Rationale: The correct answer is to take a calcium and vitamin D combination supplement. Vitamin D enhances the absorption of calcium in the body, making it an essential component for calcium utilization. Choice B is incorrect because calcium and phosphorus have an inverse relationship, where an increased level of one mineral decreases the level of the other, so taking them together may not be beneficial. Choice C is incorrect because antacids often contain magnesium, which can promote calcium loss instead of absorption. Choice D is incorrect because aspirin can alter vitamin D levels and interfere with calcium absorption, so it is not recommended when taking calcium supplements.
3. What instruction should the nurse include for a client prescribed nitroglycerin for a myocardial infarction?
- A. Take the medication only when experiencing severe chest pain.
- B. Store the medication in a dark container to protect it from light.
- C. Take the medication before engaging in physical activity that may trigger chest pain.
- D. Limit nitroglycerin use to no more than three doses in 15 minutes.
Correct answer: D
Rationale: The correct answer is D: 'Limit nitroglycerin use to no more than three doses in 15 minutes.' This instruction is crucial to prevent excessive use, which can lead to severe hypotension and other complications. Choice A is incorrect because nitroglycerin should also be used preventatively, not only during severe chest pain. Choice B is irrelevant and not a necessary instruction for nitroglycerin use. Choice C is incorrect as nitroglycerin is typically taken to prevent chest pain rather than waiting for an activity that may trigger it.
4. A child is diagnosed with acquired aplastic anemia. The nurse knows that this child has the best prognosis with which treatment regimen?
- A. blood transfusion
- B. chemotherapy
- C. bone marrow transplantation
- D. immunosuppressive therapy
Correct answer: C
Rationale: In the case of acquired aplastic anemia, bone marrow transplantation offers the best chance of cure as it replaces the abnormal stem cells with healthy ones. Blood transfusion may provide temporary relief by replacing blood cells, but it does not address the root cause of the condition. Chemotherapy may be used in some cases, but it is not the preferred treatment for acquired aplastic anemia. While immunosuppressive therapy can be effective, especially in patients who are not candidates for a bone marrow transplant, it is not the first-line treatment and does not offer the same potential for a cure as bone marrow transplantation.
5. In a client with cirrhosis admitted with jaundice and ascites, which laboratory value is most concerning?
- A. Serum bilirubin of 3.0 mg/dl
- B. Serum albumin of 3.0 g/dl
- C. Serum ammonia level of 80 mcg/dl
- D. Serum sodium level of 135 mEq/L
Correct answer: C
Rationale: A serum ammonia level of 80 mcg/dl is most concerning in a client with cirrhosis as it may indicate hepatic encephalopathy, requiring immediate intervention. Elevated ammonia levels are associated with impaired liver function and can lead to mental status changes. Serum bilirubin (Choice A) is elevated in cirrhosis but not as concerning for acute intervention as high ammonia levels. Serum albumin (Choice B) and serum sodium (Choice D) levels are important in cirrhotic patients but are not as directly associated with hepatic encephalopathy as ammonia levels.
