HESI RN
HESI Medical Surgical Exam
1. After a session of hemodialysis, the nurse should monitor the client for which of the following complications of hemodialysis?
- A. Hyperkalemia.
- B. Hypotension.
- C. Infection.
- D. Fever.
Correct answer: B
Rationale: The correct answer is 'B: Hypotension.' Hypotension is a common complication of hemodialysis because fluid removal during the process can lead to a drop in blood pressure. The nurse should closely monitor the client for signs of hypotension such as dizziness, lightheadedness, or a decrease in blood pressure readings. Choice 'A: Hyperkalemia' is incorrect because hemodialysis actually helps lower potassium levels by removing excess potassium from the blood. Choice 'C: Infection' is incorrect as it is not a direct complication of hemodialysis but rather a risk associated with invasive procedures. Choice 'D: Fever' is incorrect as fever is not a typical immediate post-hemodialysis complication unless an underlying infection is present.
2. Which of the following interventions is most appropriate for a patient with left-sided heart failure?
- A. Administering IV fluids.
- B. Administering oxygen.
- C. Administering diuretics.
- D. Administering antihypertensives.
Correct answer: B
Rationale: Administering oxygen is the most appropriate intervention for a patient with left-sided heart failure because it helps improve oxygenation. In left-sided heart failure, the heart struggles to pump oxygen-rich blood to the body, leading to inadequate oxygen supply to tissues. Administering oxygen can help alleviate symptoms of hypoxia and reduce the workload on the heart. IV fluids (Choice A) may exacerbate heart failure by increasing fluid volume, diuretics (Choice C) are used to reduce fluid overload in heart failure, and antihypertensives (Choice D) are more suitable for managing hypertension, which may be a comorbidity in heart failure but are not the primary intervention for left-sided heart failure.
3. The healthcare provider is caring for a client with diabetes insipidus. Which finding indicates that the treatment is effective?
- A. Urine output is decreased.
- B. Thirst is decreased.
- C. Weight loss is observed.
- D. Urine specific gravity is within the normal range.
Correct answer: D
Rationale: In diabetes insipidus, the body loses excessive amounts of water, leading to diluted urine with low specific gravity. Therefore, when the urine specific gravity is within the normal range, it indicates that the kidneys are properly concentrating urine, which is a sign of effective treatment for diabetes insipidus. Choices A, B, and C are incorrect because in diabetes insipidus, there is polyuria (excessive urination), persistent thirst due to fluid loss, and potential weight loss due to fluid imbalance, so these findings would not indicate effective treatment.
4. A nurse is reinforcing nutrition teaching with a client who has osteoporosis. Which of the following food selections should the nurse recommend to increase calcium in the client's diet?
- A. 1 medium apple
- B. 3 oz of lean beef
- C. 1 tbsp of cream cheese
- D. 1 cup of kale
Correct answer: D
Rationale: The correct answer is D: 1 cup of kale. Kale is rich in calcium, making it a suitable choice to increase calcium intake for individuals with osteoporosis. While fruits like apples (choice A) are nutritious, they are not high in calcium. Lean beef (choice B) is a good source of protein but not a significant source of calcium. Cream cheese (choice C) is also not a primary source of calcium compared to kale.
5. The nurse is assessing a 4-month-old infant who has just received routine immunizations. The mother reports that the baby has been fussy and has a low-grade fever since the immunizations. What is the best response by the nurse?
- A. These are common side effects and should resolve within a few days
- B. Your baby may be having an allergic reaction to the immunizations
- C. You should bring your baby to the clinic immediately for evaluation
- D. You should give your baby aspirin to help with the fever
Correct answer: A
Rationale: The correct response by the nurse is to reassure the mother that fussiness and low-grade fever are common side effects of immunizations in infants and should resolve within a few days. It is essential to educate the mother about these expected reactions to alleviate her concerns. Choice B is incorrect because allergic reactions to immunizations usually present with more severe symptoms such as difficulty breathing or swelling. Choice C is not warranted unless there are concerning symptoms present. Choice D is inappropriate as aspirin is contraindicated in infants due to the risk of Reye's syndrome.
