Fundamentals of Nursing HESI

Correct Answer: B

Rationale: The correct answer is B: Maintain alveolar surface tension. Respiratory distress syndrome in premature infants is often caused by a deficiency in surfactant, a substance that helps maintain alveolar surface tension. Without adequate surfactant, the alveoli collapse, making it difficult for the infant to oxygenate effectively. Choices A, C, and D are incorrect because stabilizing alveolar surface tension is not the issue, promoting normal pulmonary blood flow and regulating intra-cardiac pressure are not directly related to the pathophysiology of respiratory distress syndrome in premature infants.

Correct Answer: B

Rationale: When evaluating the care of an immobilized patient, the nurse should focus on assessing outcomes and response to nursing care. By comparing the patient's actual outcomes with the outcomes identified during planning, the nurse can determine the effectiveness of the interventions implemented. This process allows for a comprehensive evaluation of the care provided. Choice A is incorrect because the satisfaction of the interdisciplinary team does not directly reflect the patient's outcomes and response to care. Choice C is incorrect as it mainly focuses on the involvement of the patient's family and healthcare team, which may not provide a holistic evaluation of the patient's care. Choice D is incorrect as relying solely on objective data may lead to overlooking important subjective aspects of the patient's response and outcomes, which are also crucial in evaluating care effectively.

Correct Answer: B

Rationale: When cimetidine decreases the metabolism of imipramine, it leads to an increased concentration of imipramine in the body, which can result in imipramine toxicity. This increased risk of toxicity is the likely effect of this drug interaction. Choice A is incorrect because cimetidine's effect on imipramine metabolism does not impact the therapeutic effects of cimetidine. Choice C is incorrect because the interaction does not decrease the risk of adverse effects of cimetidine. Choice D is incorrect as the increased concentration of imipramine can lead to toxicity, not increased therapeutic effects.

Correct Answer: A

Rationale: When a client with an indwelling catheter reports a need to urinate, the nurse's initial action should be to check the catheter for patency. This is crucial to ensure that the catheter is not blocked, twisted, or kinked, which could lead to urinary retention. Reassuring the client without assessing the catheter could delay necessary interventions. Re-catheterizing the bladder with a larger-gauge catheter should not be the first step unless catheter patency is confirmed as an issue. Collecting a urine specimen for analysis is important but not the immediate priority when the client reports a need to urinate.

Correct Answer: C

Rationale: When preparing to insert an IV catheter, stroking the extremity before insertion helps to visualize veins, making it easier to locate a suitable vein for catheter insertion. Choosing the most distal site on the extremity is correct because veins more distal are preferred for IV catheter insertion. Applying a cool compress to the extremity before insertion is unnecessary and not a standard practice. Placing the tourniquet below the proposed insertion site is incorrect; the tourniquet should be placed above the proposed insertion site to help engorge the veins for easier visualization and access.
