A healthcare provider is assessing a patient with dehydration. Which finding indicates the patient's condition is worsening?

Correct Answer: B

Rationale: Tachycardia and low blood pressure are indicative of worsening dehydration in a patient. Tachycardia is the body's compensatory mechanism to maintain cardiac output in response to decreased intravascular volume, while low blood pressure reflects inadequate perfusion due to decreased fluid levels. Bradycardia and shallow respirations are not typical findings in worsening dehydration, and clear lung sounds do not directly correlate with the severity of dehydration.

Correct Answer: B

Rationale: The correct answer is to monitor the patient's skin integrity. This is crucial because diarrhea can lead to skin breakdown due to frequent bowel movements and increased moisture in the perineal area. By monitoring skin integrity, nurses can prevent skin breakdown, infection, and other associated issues. Encouraging fluid intake (Choice A) is important but not the most critical intervention. Checking electrolyte levels (Choice C) is essential but may not be the top priority at the onset. Educating the patient about infection control (Choice D) is important but secondary to preventing skin breakdown in a patient with diarrhea.

Correct Answer: B

Rationale: The most important action to ensure patient safety when administering a blood transfusion is to verify the patient's identity with two identifiers before starting the transfusion. This step is crucial to prevent transfusion errors, such as giving the blood to the wrong patient. Checking vital signs, ensuring timely administration, and confirming informed consent are also important aspects of blood transfusion safety but verifying the patient's identity is the highest priority to prevent errors.

Correct Answer: A

Rationale: The most critical lifestyle change for a patient with hypertension is to reduce salt intake. Excessive salt consumption can lead to increased blood pressure levels. While limiting alcohol consumption (Choice B) and regular exercise (Choice C) are also beneficial for managing hypertension, reducing salt intake has a more direct impact on blood pressure control. Avoiding high-cholesterol foods (Choice D) is important for heart health but may not have as significant an impact on blood pressure as reducing salt intake.

Correct Answer: D

Rationale: Crackles heard in the lung bases are most concerning in a patient with pneumonia as they suggest fluid accumulation in the lungs, indicating possible severe infection or respiratory distress. Prompt intervention is required to prevent further complications.\n\nChoice A, fever of 101°F, is common in infections like pneumonia but may not be as immediately concerning as crackles indicating fluid in the lungs.\n\nChoice B, a blood pressure of 140/90 mmHg, is within normal limits and not directly indicative of pneumonia severity.\n\nChoice C, a heart rate of 95 beats per minute, is slightly elevated but not as critical as crackles suggesting fluid in the lungs.
