Correct Answer: A

Rationale: The correct way to carry an infant with cerebral palsy experiencing muscle hypertonicity and scissoring of the legs is astride one of the mother's hips. This position helps keep the infant's legs apart, reducing muscle tightness. Strapping the infant in an infant seat, wrapping tightly in a blanket, or using the football hold under the arm does not address the specific needs related to muscle hypertonicity and scissoring of the legs in cerebral palsy.

Correct Answer: C

Rationale: The correct action for the nurse to take when unable to auscultate a pericardial friction rub in a client diagnosed with pericarditis is to ask the client to lean forward and listen again. This position brings the heart closer to the chest wall, making it easier to detect a friction rub if present. Notifying the healthcare provider is not necessary at this point as it may just be a matter of positioning for better auscultation. Documenting that the pericarditis has resolved is premature without proper assessment. Preparing to insert a unilateral chest tube is not indicated based on the absence of a friction rub.

Correct Answer: A

Rationale: The correct answer is A. Lying flat in the supine position for 12 hours after a renal biopsy helps prevent bleeding, which is crucial for the client's recovery. This position aids in applying pressure to the biopsy site, reducing the risk of bleeding and ensuring optimal healing. Choices B, C, and D do not directly relate to compliance with client teaching after a renal biopsy. Continuing oral fluids restriction, changing the dressing, or activating a patient-controlled analgesia pump are not specific instructions aimed at promoting recovery and preventing complications post renal biopsy.

Correct Answer: D

Rationale: In a sickle cell crisis, morphine is the preferred analgesic due to its potency and effectiveness in managing severe pain. Choice A is incorrect because aspirin is contraindicated in sickle cell disease due to its potential to cause a further decrease in blood flow. Choice B, Motrin (ibuprofen), is also not the ideal choice as NSAIDs can exacerbate renal complications in sickle cell patients. Choice C, Demerol (meperidine), is not recommended for sickle cell pain management due to its toxic metabolite accumulation which can cause seizures and other complications.

Correct Answer: C

Rationale: The correct action for the nurse to implement when unable to auscultate a pericardial friction rub in a client diagnosed with pericarditis is to ask the client to lean forward and listen again. Leaning forward can help bring the heart closer to the chest wall, making it easier to detect the rub. Option A (Notifying the healthcare provider) is incorrect because further assessment is needed before escalating the situation. Option B (Documenting that the pericarditis has resolved) is incorrect as the absence of a friction rub does not necessarily mean resolution. Option D (Preparing to insert a unilateral chest tube) is incorrect as this intervention is not indicated for the absence of a friction rub.
