A nurse is caring for a 59-year-old male client in the intermediate care unit.
Oxygen saturation of 56%
Crackles heard in the right lung
pH of 7.21
Tracheal deviation to the right
Correct Answer : A,D
Choice A rationale: Oxygen saturation of 56% is critically low and indicates severe hypoxemia, which requires immediate intervention to improve oxygenation and prevent life-threatening complications.
Choice D rationale: Tracheal deviation to the right suggests a possible tension pneumothorax, which is a medical emergency. It requires immediate attention to relieve the pressure on the affected lung and restore normal breathing.
Choice B rationale: Crackles heard in the right lung indicate fluid or atelectasis but are not immediately life-threatening compared to the other findings.
Choice C rationale: A pH of 7.21 indicates acidemia and respiratory acidosis but is a secondary concern compared to the immediate need to address the client's hypoxemia and potential tension pneumothorax.

Correct Answer is D
Explanation
Choice A rationale
Asking the mother about usual care practices might provide useful information, but it is not the best immediate intervention for addressing the child's dry and cracked lips and nares. Immediate action should be taken to provide relief.
Choice B rationale
Using a topical lidocaine analgesic is not appropriate for treating dryness and cracking of the lips and nares. Lidocaine is an anesthetic, not a moisturizing agent, and could cause additional irritation or adverse reactions if used improperly.
Choice C rationale
Applying petroleum jelly to the child's nose and lips is not recommended as it poses a risk of aspiration, especially in young children. Inhaling petroleum jelly can lead to respiratory issues and is therefore not a safe option.
Choice D rationale
Using a water-soluble lubricant is the best option for moisturizing and protecting the child's dry and cracked lips and nares. Water-soluble lubricants are safe for use on mucous membranes and provide effective relief without the risk of aspiration.
Correct Answer is ["B","C","D"]
Explanation
Choice B rationale: Capillary refill time of 6 seconds is significantly delayed and indicates poor peripheral perfusion. This finding suggests that the client may be experiencing decreased cardiac output or hypovolemia, which requires immediate attention to improve circulation and oxygen delivery to tissues.
Choice C rationale: Blood pressure of 90/79 mmHg with a pulse pressure of less than 40 mmHg is a critical finding. The narrow pulse pressure and hypotension indicate potential hypovolemia or shock, which must be addressed urgently to stabilize the client's hemodynamic status.
Choice D rationale: The client’s lack of urine output from the indwelling catheter is concerning and indicates potential kidney dysfunction or decreased renal perfusion. Immediate intervention is necessary to assess and manage potential underlying causes, such as hypovolemia or renal injury.
Choice A rationale: Oxygen saturation of 100% on 40% oxygen is not an immediate concern. While it is important to continue monitoring oxygen levels, the client is currently receiving adequate oxygenation.
