Correct Answer: C

Rationale: The correct answer is C: Pulmonary artery obstructive pressure (PACP). The multilumen pulmonary artery catheter measures hemodynamic pressures in the heart. When the catheter tip enters small branches of the pulmonary artery, it can assess Central Venous Pressure (A), Pulmonary Artery Capillary Pressure (B), and Pulmonary Artery Wedge Pressure (D). Pulmonary artery obstructive pressure is not a standard hemodynamic measurement and is not assessed using this catheter. It is crucial to differentiate between the various pressures measured to accurately assess the patient's cardiac status.

Correct Answer: A

Rationale: Step 1: Reassessing the wound and client's condition allows the nurse to identify any factors contributing to the lack of improvement. Step 2: It helps determine if the current care plan needs modifications or if there are underlying issues affecting healing. Step 3: This step ensures a comprehensive evaluation before making any changes to the care plan, promoting evidence-based practice. Step 4: Choosing this option aligns with the nursing process of assessment, which is crucial for making informed decisions in client care. Summary: Option A is correct as it emphasizes the importance of reassessment to gather more information and make informed decisions. Discontinuing the care plan (Option B) without assessment can be harmful. Increasing dressing changes (Option C) may not address the underlying issue. Referring immediately (Option D) may be premature without reassessment.

Correct Answer: A

Rationale: The correct answer is A: 30 minutes before breakfast. Glyburide is a sulfonylurea medication that stimulates insulin release from the pancreas, enhancing glucose uptake. Taking it before breakfast ensures peak insulin levels coincide with the postprandial glucose spike, aiding in glucose control throughout the day. Option B is incorrect as taking it after dinner may lead to hypoglycemia during sleep. Option C is incorrect as midmorning is not an optimal time for a sulfonylurea dose. Option D is incorrect as taking it at bedtime may also increase the risk of hypoglycemia overnight.

Correct Answer: D

Rationale: The correct answer is D: absence seizures. Barbiturate anticonvulsants are not effective in treating absence seizures because they can worsen this type of seizure by suppressing brain activity. Barbiturates are typically used to treat tonic-clonic seizures and partial seizures, but not absence seizures. Febrile seizures are typically managed without barbiturate anticonvulsants. In summary, barbiturate anticonvulsants are effective in treating partial seizures and tonic-clonic seizures, but not absence seizures or febrile seizures due to their mechanisms of action and potential side effects.

Correct Answer: C

Rationale: The correct answer is C: Hypercalcemia. In bone cancer, there can be excessive release of calcium from the bones, leading to elevated blood calcium levels. This can result in various complications such as kidney stones, cardiac arrhythmias, and weakness. Hyperkalemia (choice A) is not commonly associated with bone cancer. Hyponatremia (choice B) is more commonly seen in conditions like heart failure or kidney disease. Hypomagnesemia (choice D) is not a common electrolyte disturbance in bone cancer.
