Correct Answer: B

Rationale: The correct answer is B: Increased hematocrit. Increased hematocrit indicates hemoconcentration, which is a sign of fluid volume deficit. When there is a decrease in fluid volume in the body, the blood becomes more concentrated, leading to an increase in hematocrit levels. Choices A, C, and D are incorrect because decreased BUN levels, increased white blood cell count, and decreased hematocrit are not indicative of fluid volume deficit.

Correct Answer: B

Rationale: A pulse deficit is a crucial finding in clients with dysrhythmias as it indicates ineffective cardiac contractions. A pulse deficit occurs when the apical heart rate is faster than the radial pulse rate, suggesting that some heartbeats are not generating a pulse. This can be a sign of serious heart conditions like atrial fibrillation or heart failure. The other options, such as an increased heart rate (choice A), elevated blood pressure (choice C), and bounding pulse (choice D), do not specifically indicate ineffective cardiac contractions and are not directly associated with dysrhythmias.

Correct Answer: C

Rationale: The correct answer is C. If sterile solution splashes onto the sterile field, it is considered contaminated. Changing gloves in this situation ensures that the sterility of the dressing change is maintained. Choice A is incorrect as non-sterile gloves would introduce contaminants. Choice B is incorrect as layering gloves can increase the risk of contamination. Choice D is incorrect as covering the sterile field with a sterile drape is not the appropriate action to take in response to contamination.

Correct Answer: C

Rationale: The correct answer is C because placing a clean dressing over the saturated one helps maintain wound integrity and prevents further tissue damage. Choice A is incorrect as applying direct pressure to the wound is correct for controlling bleeding but not for dressing changes. Choice B is incorrect because removing dressings may disrupt wound healing and increase the risk of infection. Choice D is incorrect since applying alcohol to the wound can cause further irritation and damage to the tissues.

Correct Answer: B

Rationale: Bowel inflammation can reduce the absorption of oral medications, leading to decreased effectiveness. In this case, the decrease in the effectiveness of the arthritis medication could be attributed to impaired absorption due to bowel inflammation. Choices A, C, and D are incorrect because increased activity level, long-term use of the medication, and history of dehydration are not directly associated with a decrease in medication effectiveness related to absorption issues.
