HESI Fundamentals Exam

Correct Answer: C

Rationale: Encouraging bed rest and quiet activities is crucial for a child recovering from a splenectomy with low hemoglobin and hematocrit levels. This approach helps conserve energy, promotes healing, and allows the body to focus on rebuilding red blood cells. Limiting milk and milk products (Choice A) is not directly related to improving the child's condition. Encouraging bed rest and quiet activities (Choice B) is appropriate as it helps in conserving energy and preventing physical exertion. Promoting a diet rich in iron (Choice D) is beneficial for improving hemoglobin levels in the long term, but immediate rest and recovery take precedence in this scenario.

Correct Answer: A

Rationale: A decrease in heart rate can indicate improved fluid balance and successful treatment of fluid volume deficit. When a client is experiencing fluid volume deficit, the heart rate typically increases as a compensatory mechanism to maintain cardiac output. As fluid volume is restored and the deficit is corrected, the heart rate should decrease back towards a normal range. Choices B, C, and D are less likely to be directly related to the successful treatment of fluid volume deficit. An increase in blood pressure may occur as a compensatory response to fluid volume deficit; a decrease in respiratory rate is not a typical indicator of fluid volume deficit correction; and an increase in urine output can be a sign of improved kidney function but may not directly reflect fluid volume status.

Correct Answer: B

Rationale: When assessing body alignment for an immobilized patient, the nurse should use the lateral position. This position helps in assessing alignment and preventing complications such as pressure ulcers. The supine position (Choice A) may not provide an accurate assessment of body alignment in an immobilized patient. While a lateral position with positioning supports (Choice C) may be used for comfort, it is not specifically for assessing body alignment. Using the supine position without a pillow under the patient's head (Choice D) is not ideal for assessing body alignment in an immobilized patient as it may not accurately reflect the patient's overall alignment.

Correct Answer: A

Rationale: Refrigeration can kill the ova and parasites present in the stool specimen, leading to inaccurate test results. Storing the specimen in a cold environment can disrupt the integrity of the parasites and ova, affecting the accuracy of the test. Collecting the specimen in a sterile container (Choice B) is the correct procedure to prevent external contamination. Delaying the collection of the specimen (Choice C) may affect the freshness of the sample but does not directly impact the test results. Using a non-contaminated collection container (Choice D) is essential to maintain the sample's integrity but does not relate to the risk of killing ova and parasites through refrigeration.

Correct Answer: C

Rationale: The Z-track method is used to minimize tissue irritation by sealing the medication in the muscle. This technique helps prevent leakage of the medication into subcutaneous tissue, reducing the risk of irritation and staining at the injection site. Option A about decreasing the risk of injecting medication into a blood vessel is not correct as the primary purpose of the Z-track method is to prevent tissue irritation. Option B stating it delays medication absorption is incorrect as the Z-track method does not affect the rate of medication absorption. Option D mentioning it accelerates medication excretion is incorrect as the Z-track method does not impact medication excretion but rather focuses on minimizing tissue irritation.
