Correct Answer: A

Rationale: Specific gravity measures the concentration of solutes in the urine, reflecting the kidney's ability to concentrate or dilute urine. Choice B, bacteria in the urine, is incorrect because specific gravity does not measure bacterial presence. Choice C, pH level of the urine, is incorrect as it refers to the acidity or alkalinity of the urine, not its specific gravity. Choice D, glucose in the urine, is incorrect as specific gravity does not directly measure glucose levels in urine.

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: A

Rationale: The appropriate nursing action when an irregularity in the heart rate is observed is to count the apical pulse rate for a full minute and describe the rhythm in the chart. This approach helps in obtaining an accurate assessment of the irregularities present. Measuring the blood pressure (Choice B) is important but not the immediate priority when an irregular heart rate is noted. Performing an ECG (Choice C) may be necessary but is a more advanced intervention that should follow the initial assessment. Rechecking the heart rate after 5 minutes (Choice D) may delay potential interventions for addressing the irregularity, making it less appropriate than the immediate assessment and documentation of the pulse rhythm.

Correct Answer: A

Rationale: Encouraging the client to use an incentive spirometer regularly is crucial in preventing postoperative complications after abdominal surgery. This action helps prevent atelectasis by promoting lung expansion and improving air exchange in the lungs, reducing the risk of respiratory complications. Assisting the client in ambulating early is important for preventing issues like deep vein thrombosis but may not directly address respiratory concerns postoperatively. Positioning the client in high Fowler's position can help with respiratory distress but is not as specific to preventing postoperative respiratory complications as using an incentive spirometer. While encouraging the client to cough and deep breathe is generally beneficial for lung expansion, using an incentive spirometer is more effective and targeted in preventing atelectasis after abdominal surgery.

Correct Answer: A

Rationale: Filling the ice bag two-thirds full is the correct action as it ensures the effectiveness of the ice application while allowing some space for the ice to move and conform to the injury. Choice B is incorrect because the ice bag should be applied with a barrier like a cloth to prevent direct contact with the skin, which can lead to ice burns. Choice C is wrong as ice should typically be applied for 20 minutes at a time to avoid tissue damage. Choice D is also incorrect as ice is preferred over frozen gel packs for immediate sports injury management.
