A nurse is assessing a client’s pulmonary artery wedge pressure (PAWP). The nurse should recognize that an elevated PAWP indicates which of the following complications?
Cardiogenic shock
Left ventricular failure
Hypotension
Hypovolemia
The Correct Answer is B
Choice A reason: Cardiogenic shock involves reduced cardiac output, typically with low PAWP due to decreased preload from poor heart function. Elevated PAWP reflects left atrial pressure buildup, not characteristic of cardiogenic shock alone, which is distinct from heart failure, requiring specific hemodynamic management.
Choice B reason: Elevated PAWP indicates left ventricular failure, where the heart cannot pump blood effectively, causing pulmonary congestion. This increases left atrial pressure, leading to pulmonary edema, a hallmark of heart failure. Diuretics and inotropes are needed to reduce fluid overload and improve cardiac function.
Choice C reason: Hypotension is a symptom, not a direct complication of elevated PAWP. It may occur in heart failure due to reduced cardiac output, but elevated PAWP specifically signals left heart dysfunction, not hypotension itself, which is a systemic response rather than a primary cardiac issue.
Choice D reason: Hypovolemia reduces blood volume, lowering PAWP due to decreased preload. Elevated PAWP suggests fluid overload or left ventricular dysfunction, not hypovolemia, which presents with low central venous pressure and dehydration signs, requiring fluid resuscitation rather than management of heart failure.

Correct Answer is B
Explanation
Choice A reason: Comparing the medication label to the provider’s prescription three times is a safety step during administration, not reconciliation. Reconciliation verifies the client’s home medications against new orders to prevent errors like omissions or duplications. This action occurs post-reconciliation, focusing on administration accuracy, not the initial verification of the medication list.
Choice B reason: Medication reconciliation involves comparing the client’s home medication list to admission prescriptions to ensure continuity and accuracy. This process identifies discrepancies, such as missed medications or incorrect doses, preventing adverse drug events. It requires verifying with the client or family and cross-checking provider orders, making it the cornerstone of safe transitions in care settings.
Choice C reason: Administering medications to treat a condition to the actual prescriptions is unclear and not part of reconciliation. Reconciliation focuses on verifying and documenting medications, not administering them. This option does not align with the systematic process of ensuring all medications are correctly prescribed upon admission, making it incorrect.
Choice D reason: Ensuring administration within 3 hours of the scheduled time relates to medication administration protocols, not reconciliation. Reconciliation verifies the accuracy of the medication list before administration. This step is about timing, not the verification process critical to preventing errors during care transitions, rendering it irrelevant to the task.
Correct Answer is A
Explanation
Choice A reason: Decreased serotonin levels are linked to depression, as serotonin regulates mood in the brain’s limbic system. Antidepressants like SSRIs increase serotonin, alleviating low mood and anhedonia, making this client a prime candidate for therapy to address neurochemical imbalances in depression.
Choice B reason: Decreased cortisol is not directly tied to depression requiring antidepressants. Cortisol dysregulation may occur in stress disorders, but antidepressants target serotonin or norepinephrine, not adrenal function, making this client less suitable for antidepressant therapy based on this imbalance.
Choice C reason: Elevated dopamine is linked to schizophrenia or mania, not depression. Antidepressants target serotonin or norepinephrine, not dopamine. This client may need antipsychotics or mood stabilizers, not antidepressants, as dopamine excess does not indicate depressive pathology requiring such therapy.
Choice D reason: Elevated thyroid levels suggest hyperthyroidism, mimicking anxiety, not depression. Antidepressants are not indicated, as treatment targets thyroid function. Depression may coexist, but thyroid correction is prioritized, making this client unsuitable for primary antidepressant therapy based on this finding.
