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: B

Rationale: The correct answer is B. Rheumatic fever often follows a strep throat infection, which is why the nurse should suspect this association. Strep throat is caused by Group A Streptococcus bacteria, which can trigger an abnormal immune response leading to rheumatic fever. Choices A, C, and D are incorrect because chickenpox, ear infections, and fungal skin infections are not typically associated with rheumatic fever.

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.
