Correct Answer: A

Rationale: A halo of erythema on the surrounding skin may indicate an infection or inflammation of the wound site, which is critical to report to the surgeon. Erythema, redness, and warmth are signs of inflammation that could potentially be a sign of an infected wound. Serous drainage is a common and expected finding in healing wounds, indicating a normal healing process. Edema around the wound might be expected due to the body's response to tissue injury. The absence of granulation tissue in a wound healing by secondary intention may not be an immediate concern as it forms during the later stages of wound healing.

Correct Answer: C

Rationale: The correct answer is C: Friction. The amount of friction is crucial in effective hand hygiene to remove microorganisms. Rubbing hands together with friction helps to dislodge and remove dirt, oils, and microorganisms. While temperature and soap are important factors in hand hygiene, the mechanical action of friction plays a more significant role in physically removing contaminants. Time is also important in hand hygiene practice, but without adequate friction, the effectiveness of the process is compromised.

Correct Answer: D

Rationale: Securing the catheter to the client's thigh is the correct action to prevent CAUTIs. By securing the catheter, movement is minimized, reducing the risk of introducing bacteria into the urinary tract. Choice A is incorrect because routine irrigation of the catheter is not recommended as it can increase the risk of infection. Choice B is incorrect as emptying the catheter bag every 8 hours is important for proper drainage but does not directly prevent CAUTIs. Choice C is incorrect because cleaning the perineal area with antiseptic solution does not address the main source of CAUTIs related to catheter care.

Correct Answer: D

Rationale: The correct answer is D. Sealing the lips around the mouthpiece is crucial for the proper use of an incentive spirometer as it helps ensure effective delivery of the inhaled medication. Choice A has been corrected to reflect the importance of sealing the lips. Choices B and C are incorrect because using the spirometer as needed throughout the day and inhaling slowly and deeply, although beneficial, do not directly address the essential technique of sealing the lips around the mouthpiece.

Correct Answer: A

Rationale: The correct answer is A: Hypertension. Pheochromocytoma is characterized by the overproduction of catecholamines, leading to symptoms such as hypertension. Bradycardia (Choice B) is not typical in pheochromocytoma as increased catecholamines usually lead to tachycardia. Hypoglycemia (Choice C) and weight gain (Choice D) are not commonly associated symptoms of pheochromocytoma.
