Correct Answer: C

Rationale: A platelet count of 90,000/mm³ indicates thrombocytopenia, which increases the risk of bleeding and requires immediate intervention. Thrombocytopenia can lead to serious bleeding complications, so it is crucial to address this finding promptly. A low white blood cell count (choice A) may indicate neutropenia but is not as immediately life-threatening as severe thrombocytopenia. A hemoglobin level of 8 g/dL (choice B) would require intervention but is not as urgent as addressing a critically low platelet count. A serum potassium level of 3.5 mEq/L (choice D) is on the lower side of normal but does not pose an immediate risk to the client's safety compared to severe thrombocytopenia.

Correct Answer: A

Rationale: The correct answer is A, Methylergonovine. Methylergonovine is contraindicated in clients with preeclampsia due to the risk of hypertension. Misoprostol (choice B), Dinoprostone (choice C), and Oxytocin (choice D) are appropriate medications for managing postpartum hemorrhage and are not contraindicated in clients with preeclampsia.

Correct Answer: A

Rationale: The correct answer is to monitor INR levels. INR levels are the most critical indicator for monitoring bleeding risk in patients on warfarin. INR stands for International Normalized Ratio and specifically measures the clotting tendency of the blood. Monitoring hemoglobin levels, potassium levels, or platelet count are not as directly relevant to assessing bleeding risk in patients on warfarin.

Correct Answer: A

Rationale: Corrected Rationale: Administering prescribed analgesics is the most effective way to manage acute pain. Analgesics help in reducing or eliminating pain quickly and efficiently. Repositioning the patient may be helpful in certain cases to relieve discomfort, but it is not the primary intervention for managing acute pain. Non-pharmacological interventions can be beneficial as adjuncts to pain management, but in cases of acute pain, administering analgesics is the priority. Administering IV fluids may be necessary for certain conditions but is not the primary intervention for managing acute pain.

Correct Answer: A

Rationale: The nurse should document the time the medication was given in the client's medical record when an incorrect dose is administered. Recording the time is crucial for establishing the sequence of events accurately. Choices B, C, and D, though important, are not directly relevant to documenting the incident of administering an incorrect dose of medication. The client's response to the medication, the actual dose administered, and the reason for the error may be documented for overall patient care but are not specifically required in the incident report for an incorrect dose.
