Correct Answer: A

Rationale: Complete bedrest is necessary for a pregnant client with mitral stenosis Class III to reduce the workload on the heart, lower oxygen consumption, and prevent complications associated with cardiac conditions like mitral stenosis. By remaining in bed, the client can help maintain cardiac function and promote a safer pregnancy outcome. Choice B is incorrect as it does not provide a specific reason related to the client's medical condition. Choice C is not addressing the medical necessity of bedrest for this particular client. Choice D is irrelevant and does not explain the importance of bedrest for a pregnant client with mitral stenosis Class III.

Correct Answer: A

Rationale: Cephalhematoma is the accumulation of blood between the periosteum and skull, often due to birth trauma, and typically resolves within weeks. It is a common finding in newborns and is not usually a cause for concern as it gradually resolves without specific treatment. Subarachnoid hematoma and subdural hematoma are different conditions that present with distinct characteristics and require different management strategies. Therefore, the correct answer is A. Subarachnoid hematoma is typically found in the subarachnoid space and requires immediate intervention, not just observation like cephalhematoma. Molding refers to the shaping of the fetal head during passage through the birth canal and is a temporary change, not a collection of blood like in cephalhematoma. Subdural hematoma is located beneath the dura mater and is associated with significant complications, unlike the self-limiting nature of cephalhematoma.

Correct Answer: D

Rationale: In the scenario presented, the client is exhibiting signs and symptoms of severe preeclampsia, including hypertension, proteinuria, facial and hand swelling, visual disturbances, and a severe headache. The medication of choice for preventing seizures in preeclampsia is magnesium sulfate. This drug helps to prevent and control seizures in clients with preeclampsia, making it the most appropriate option for this client. Clonidine hydrochloride (Choice A) is an antihypertensive medication used for managing hypertension but is not the first-line treatment for preeclampsia. Carbamazepine (Choice B) is an anticonvulsant used for seizure disorders like epilepsy and is not indicated for preeclampsia. Furosemide (Choice C) is a diuretic used to manage fluid retention but is not the drug of choice for treating preeclampsia.

Correct Answer: A

Rationale: In a postpartum client exhibiting symptoms of a spinal headache, applying an abdominal binder is a priority action. The abdominal binder can help reduce the severity of a spinal headache by increasing intra-abdominal pressure, which may relieve pressure on the dural sac and alleviate symptoms. This intervention can be performed promptly by the nurse to provide immediate relief while waiting for further evaluation and management by the anesthesiologist. Cleansing the spinal injection site (Choice B) is not the priority in this situation as the headache is likely due to a dural puncture during epidural anesthesia rather than infection. Inserting an indwelling Foley catheter (Choice C) and placing procedure equipment at the bedside (Choice D) are not the appropriate actions to address a spinal headache and should not take precedence over applying an abdominal binder.

Correct Answer: B

Rationale: In a child with a sickle cell crisis, the priority intervention is to initiate normal saline IV at 50 ml/hr to manage dehydration and help alleviate pain. This intervention helps improve hydration status and supports the circulation of sickled red blood cells, reducing the risk of vaso-occlusive episodes and associated pain. Obtaining a culture of any sputum or wound drainage (Choice A) may be necessary but is not the initial priority. Administering a loading dose of penicillin IM (Choice C) is important but not the first intervention. Administering the initial dose of folic acid PO (Choice D) is beneficial but does not address the immediate need for hydration in a sickle cell crisis.
