Correct Answer: C

Rationale: In a client diagnosed with a pulmonary embolism experiencing a reduction in arterial oxygen saturation level and dyspnea, the priority nursing diagnosis would be Impaired Gas Exchange. This is because a pulmonary embolism can obstruct blood flow and prevent proper gas exchange in the lungs. Dyspnea and reduced oxygen saturation levels indicate inadequate gas exchange, which can lead to hypoxia. Prioritizing this nursing diagnosis will ensure that interventions are focused on improving oxygenation and respiratory function to prevent further complications.

Correct Answer: B

Rationale: Asystole is the absence of any cardiac electrical activity, and it is a non-shockable rhythm. In the case of asystole, defibrillation would not be effective. The next appropriate action would be to continue high-quality CPR and administer epinephrine according to the advanced cardiac life support (ACLS) protocol. Additionally, assessing the client's pulse is crucial to determine if there is any return of spontaneous circulation (ROSC) following CPR and medication administration. Checking the cardiac monitor electrodes ensures proper attachment and accurate monitoring of the client's cardiac rhythm but may not directly impact the management of asystole.

Correct Answer: B

Rationale: B. Coach in nonpharmacologic pain management techniques: The client's vital signs indicate they may be experiencing pain as evidenced by an elevated heart rate (P 119), which can be addressed initially with nonpharmacologic pain management techniques. This approach can help reduce pain and anxiety without the immediate need for medication.

Correct Answer: A

Rationale: When auscultating the apical pulse in pediatric clients, the nurse should place the stethoscope at the fifth intercostal space at the midclavicular line. This location is where the apex of the heart is located in pediatric clients and provides the most accurate assessment of the apical pulse. Placing the stethoscope at the left nipple (B) or right nipple (C) would not provide an accurate assessment of the apical pulse location. Auscultating at the eighth intercostal space (D) would be too low and not capture the apical pulse accurately.

Correct Answer: B

Rationale: Calcium is essential in bone healing as it is a major component of bone tissue. Adequate calcium intake is crucial for maintaining bone density and strength, which is particularly important during the healing process of a fractured bone. Calcium plays a key role in the mineralization of bone tissue, helping in the formation of new bone and repair of the fractured area. Therefore, teaching the patient about the importance of sufficient calcium intake is vital for promoting bone healing and recovery.
