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.

Correct Answer: D

Rationale: The correct procedure for applying sterile gloves is to do so before touching any sterile equipment or surfaces. This helps maintain the sterility of the gloves. Choices A, B, and C are incorrect because they suggest incorrect sequences that may compromise the sterility of the gloves. Using non-sterile gloves first can introduce contamination, putting on gloves before a gown can lead to contamination of the gloves during gowning, and applying gloves after donning a mask can risk contamination of the gloves from the mask.

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 most appropriate response for the nurse when a client asks about a medication is to refer the client to the healthcare provider for more information. This ensures that the client receives accurate and detailed information from the appropriate source. Providing detailed information or a brief explanation as choices A and C suggest may not be within the nurse's scope of practice and could potentially lead to misinformation or confusion. Asking another nurse to explain the medication, as in choice D, may not guarantee accurate information, so it is best to involve the healthcare provider directly.

Correct Answer: B

Rationale: Correct hand hygiene is crucial for preventing the spread of infections and ensuring patient safety. When a nurse observes another healthcare worker skipping hand hygiene practices, it is essential to report this behavior to the supervisor. Reporting ensures that appropriate action is taken to address the issue and maintain a safe environment for patients. Ignoring the situation (Choice A) may compromise patient safety. Discussing the issue directly with the nurse (Choice C) may not always be effective in ensuring compliance. Doing nothing and continuing with patient care (Choice D) disregards the importance of infection control protocols.
