Correct Answer: A

Rationale: Clonidine can lower blood pressure, so a BP of 90/76 mm Hg may indicate that it is unsafe to administer another dose. In this situation, the low blood pressure reading indicates that the client is already experiencing hypotension, which is a common side effect of clonidine. Administering more clonidine could further lower the blood pressure, leading to potential complications. The heart rate, respiratory rate, and temperature are within normal limits and do not serve as contraindications for administering clonidine in this scenario.

Correct Answer: A

Rationale: The correct answer is A. Dark, tarry stools may indicate gastrointestinal bleeding, a potentially life-threatening condition that requires immediate attention. Visiting this client first is crucial for prompt assessment and intervention. Choices B, C, and D do not present immediate life-threatening conditions that require urgent attention compared to the potential emergency indicated by dark, tarry stools.

Correct Answer: D

Rationale: Assessing fundal tone and lochia flow is crucial in the early detection and prevention of postpartum hemorrhage. Fundal tone helps identify uterine atony, a common cause of postpartum hemorrhage, while monitoring lochia flow can indicate excessive bleeding. Cold packs on the perineum, although helpful for pain and swelling, are not the priority in this situation. Pain assessment and observing interactions with infants are important but secondary to assessing for signs of postpartum hemorrhage.

Correct Answer: B

Rationale: The correct answer is B: Muscle cramping. SIADH causes dilutional hyponatremia due to increased ADH release. Demeclocycline is used to block the action of ADH. Muscle cramping can indicate electrolyte imbalances related to hyponatremia, which should be reported to the healthcare provider. Insomnia, increased appetite, and anxiety are not typically associated with the side effects or complications of demeclocycline or SIADH.

Correct Answer: A

Rationale: The correct action for the charge nurse to take is to call the healthcare provider who wrote the illegible prescriptions. It is crucial to clarify illegible prescriptions directly with the provider to ensure patient safety and prevent medication errors. Option B, attempting to clarify with the pharmacist, may lead to misinterpretation and is not the recommended first step. Administering the medications as prescribed without clarity can jeopardize patient safety, making option C incorrect. Asking another healthcare provider for clarification (option D) may not be effective as the responsibility lies with the provider who wrote the prescription.
