Correct Answer: B

Rationale: The correct answer is to observe the mother breastfeeding her infant. This action is essential to ensure that the infant is feeding well and to assess maternal-infant bonding. Administering the rubella vaccine subcutaneously (Option A) is not the immediate priority in this scenario as assessing breastfeeding is more crucial. Calling the nursery for the infant's blood type result (Option C) is premature and not the next appropriate step, as it does not address the immediate needs of the newborn. Administering Vicodin one tablet for pain (Option D) is not indicated without further assessment or indication of pain, making it an incorrect choice at this time.

Correct Answer: A

Rationale: Cushingoid side effects are characteristic of excess corticosteroid use, such as dexamethasone. These include moon face (rounding of the face), slow wound healing, muscle wasting, and sodium and water retention. Options B, C, and D describe symptoms that are not typically associated with Cushingoid side effects. Tachycardia, hypertension, weight loss, heat intolerance, nervousness, restlessness, tremor (Option B) are not typical of Cushingoid effects, while bradycardia, weight gain, cold intolerance, myxedema facies, and periorbital edema (Option C) are more indicative of hypothyroidism. Hyperpigmentation, hyponatremia, hyperkalemia, dehydration, and hypotension (Option D) are not classical features of Cushingoid side effects.

Correct Answer: A

Rationale: The priority nursing intervention for a client with a tracheostomy on mechanical ventilation is to suction the tracheostomy as needed. Suctioning is essential to maintain a clear airway and prevent respiratory distress. While ensuring tracheostomy ties are secure (choice B) is important, it is not as urgent as airway maintenance. Providing humidified oxygen (choice C) is beneficial but does not address the immediate need for airway clearance. Cleaning exudate around the tracheostomy site (choice D) is important for hygiene but takes precedence over ensuring airway patency through suctioning.

Correct Answer: C

Rationale: Clients with limited mobility are at the highest risk for developing pressure ulcers due to prolonged pressure on specific areas of the body. This constant pressure can lead to tissue damage and ultimately result in pressure ulcers. While age and medical conditions such as diabetes and a history of stroke can contribute to the risk of pressure ulcers, limited mobility is the most significant factor as it directly affects the ability to shift positions and relieve pressure on vulnerable areas of the body. Therefore, the 65-year-old client with limited mobility is at the highest risk compared to the other clients. The 50-year-old client with a fractured femur may have limited mobility due to the injury, but it is temporary and may not be as prolonged as chronic limited mobility. The 30-year-old client with diabetes mellitus and the 70-year-old client with a history of stroke are at risk for developing pressure ulcers, but their conditions do not directly impact their ability to shift positions and alleviate pressure like limited mobility does.

Correct Answer: D

Rationale: When urine flows into the tubing during the insertion of an indwelling urinary catheter, it confirms proper catheter placement. The next step should be to inflate the balloon with the specified amount of sterile water to secure the catheter in place. Documenting the color and clarity of the urine (choice A) is important for assessment but not the immediate next action. Inserting the catheter further (choice B) without securing it could cause harm. Asking the client to breathe deeply (choice C) is not relevant to this situation.
