A nurse is caring for a client who will be having surgery. Which of the following is a nurse’s role when obtaining informed consent?

Inform the client that consent cannot be withdrawn once given.

Identify the risks or discomforts of the surgery.

Ensure the client understands the procedure and voluntarily agrees.

Provide a detailed explanation of the surgical technique.

Answer and Explanation

The Correct Answer is C

Choice A reason: Informing the client that consent cannot be withdrawn is incorrect, as clients can revoke consent at any time before or during the procedure. This misrepresents patient rights, making it an unethical and illegal statement for the nurse’s role.
Choice B reason: Identifying risks or discomforts is the surgeon’s responsibility, not the nurse’s, during consent. The nurse verifies understanding and voluntariness, not provides risk details, so this action is outside the nurse’s scope, making it incorrect.
Choice C reason: Ensuring the client understands the procedure and voluntarily agrees is the nurse’s role when witnessing consent. This verifies informed, autonomous decision-making, aligning with legal and ethical standards, making it the correct responsibility for the nurse.
Choice D reason: Providing a detailed surgical technique explanation is the surgeon’s role, not the nurse’s. The nurse ensures comprehension and consent, not technical details, so this action exceeds the nurse’s scope during consent, making it incorrect.

Correct Answer is A

Explanation

Choice A reason: Smoked salmon is high in tyramine, which phenelzine, an MAOI, prevents from being metabolized. This risks hypertensive crisis due to norepinephrine release, potentially causing stroke or cardiovascular complications. Avoiding tyramine-rich foods is critical for safety in clients on MAOI therapy.
Choice B reason: Cottage cheese is low in tyramine, safe for phenelzine users. Unlike aged cheeses, fresh dairy poses minimal risk of hypertensive crisis, as it lacks significant tyramine content. MAOIs require avoiding high-tyramine foods, making cottage cheese an acceptable dietary choice for these clients.
Choice C reason: Grapefruit affects CYP450 enzymes, interacting with some drugs, but is not contraindicated with phenelzine. It lacks significant tyramine, so it does not trigger hypertensive crises. Avoidance is unnecessary, as it does not impact MAOI metabolism or related cardiovascular risks.
Choice D reason: Fresh apples are low in tyramine and safe for phenelzine users. MAOIs require avoiding tyramine-rich foods like aged meats, but fresh fruits do not cause hypertensive crises, as they lack amino acids interacting with MAOI metabolism, making them safe for consumption.

A. Dehydration is associated with gastroesophageal reflux. B. Dehydration is caused by decreased hemoglobin and hematocrit. C. Dehydration can increase the risk for preterm labor. D. Dehydration is treated with calcium supplements.

Correct Answer is C

Explanation

Choice A reason: Dehydration is not directly associated with gastroesophageal reflux, which involves gastric acid backflow. Dehydration affects fluid balance, not reflux mechanisms, so this statement is inaccurate and irrelevant to preterm contractions, making it incorrect.
Choice B reason: Dehydration is not caused by decreased hemoglobin and hematocrit; rather, it may elevate these due to hemoconcentration. This statement reverses the relationship, making it factually incorrect and unrelated to preterm labor risks.
Choice C reason: Dehydration can increase preterm labor risk by reducing uterine blood flow and triggering contractions via oxytocin release. This evidence-based link supports hydration as a preventive measure, making it the correct statement for teaching in this scenario.
Choice D reason: Dehydration is treated with fluid replacement, not calcium supplements, which address bone health or specific deficiencies. This treatment is irrelevant to dehydration or preterm labor, making it an incorrect and inappropriate recommendation.
