Correct Answer: A

Rationale: 1. Increased sputum production is a sign of COPD exacerbation due to worsening inflammation and mucus production. 2. Decreased respiratory rate is not typical in COPD exacerbation as patients often experience increased respiratory effort. 3. Low blood pressure is not a common sign of COPD exacerbation and is more likely related to other conditions or medications. 4. High fever is not a typical sign of COPD exacerbation and could indicate an infection or other underlying issue.

Correct Answer: B

Rationale: Rationale: B is correct because patients with CKD often have difficulty excreting potassium, so limiting high potassium foods is crucial to prevent hyperkalemia. A is incorrect because increasing potassium intake is not recommended. C is incorrect as excessive protein intake can worsen kidney function. D is incorrect because CKD patients typically have fluid restrictions to prevent fluid overload and electrolyte imbalances.

Correct Answer: B

Rationale: The correct answer is B: Encouraging early ambulation. Early ambulation helps prevent complications such as blood clots, improves circulation, aids in lung expansion, and promotes faster recovery. Pain management is important but encouraging mobility is a priority. Administering IV antibiotics is not necessary unless there is an infection present. Monitoring for signs of deep vein thrombosis is important but encouraging ambulation is a proactive approach to prevent its occurrence.

Correct Answer: A

Rationale: The correct answer is A. A blood pressure reading of 160/100 mm Hg is most concerning because it falls within the hypertensive crisis range, indicating severely elevated blood pressure that requires immediate medical attention to prevent complications like stroke or heart attack. Choices B, C, and D are within the prehypertension or mild hypertension ranges and are not as immediately concerning.

Correct Answer: A

Rationale: The correct answer is A: Ear. Examining the ear first is crucial in infants as it allows the nurse to assess for any signs of infection or abnormalities that could impact the infant's overall health. Ear infections are common in infants and can lead to serious complications if not detected early. By examining the ear first, the nurse can promptly address any issues and provide appropriate treatment. Summary of why other choices are incorrect: - B: Nose - While examining the nose is important, it is not the priority in infants as ear issues are more common and can have immediate implications on health. - C: Throat - Throat examination is important but typically follows ear examination in infants, as ear infections are more prevalent. - D: Abdomen - Abdominal examination is important for overall health assessment but is not the initial area to examine in infants as ear issues take precedence due to their frequency and potential impact.
