Correct Answer: B

Rationale: The correct answer is B: 'Suppression of airway mucus production.' Methylprednisolone, a corticosteroid, is known to suppress airway mucus production. While corticosteroids can enhance the responsiveness of beta2 receptors, they are not directly involved in the suppression of these receptors (Choice A). Corticosteroids can lead to adverse effects such as bone loss, rather than fortification of bones (Choice C). They can also increase the risk of infections like candidiasis but do not directly suppress it (Choice D). Therefore, the most expected pharmacological action of methylprednisolone therapy is the suppression of airway mucus production.

Correct Answer: B

Rationale: The correct action for the nurse to take is to respectfully deny the grandparent's request. In healthcare settings, strict security protocols are in place to ensure the safety of newborns. Only individuals with proper identification bracelets are allowed to transport newborns to prevent unauthorized individuals from taking them. Contacting the mother for verification would be time-consuming and may not be feasible immediately. Escorting the grandparent and newborn without proper identification would violate security protocols and compromise the newborn's safety. Notifying security should be done only if there is a threat or concern for safety, which is not the case in this scenario. Therefore, the best course of action is for the nurse to respectfully deny the grandparent's request to uphold the safety and security measures in place.

Correct Answer: D

Rationale: Physician assistants are healthcare providers who are licensed to prescribe medications. They have the legal ability to give telephone orders for medications. Nurse midwives primarily focus on providing prenatal care and assisting during labor and delivery. Physical therapists specialize in rehabilitation services. Pharmacists dispense medications and provide medication counseling. Therefore, among the options provided, physician assistants are the correct choice for giving telephone medication prescriptions.

Correct Answer: A

Rationale: Corrected Rationale: The nurse should encourage the client to use the PCA pump before activities like dressing changes, which are likely to cause pain, to ensure effective pain management. Monitoring the client's respiratory status (Choice B) is important but not the priority in this scenario. Providing oxygen therapy (Choice C) is not a routine intervention for all clients on PCA unless specifically indicated. Ensuring the PCA pump is functioning properly (Choice D) is essential, but encouraging the client to use the PCA before painful activities takes precedence to manage pain effectively.

Correct Answer: C

Rationale: Edema is a common sign of fluid overload. When the body retains more fluid than it excretes, it can lead to edema, which is swelling caused by excess fluid trapped in body tissues. Weight gain, not weight loss, is typically associated with fluid overload due to the retained fluids. Decreased blood pressure is more commonly associated with dehydration rather than fluid overload. Increased urine output is a sign of the body trying to eliminate excess fluids, which is contrary to the signs of fluid overload.
