Correct Answer: C

Rationale: The most pertinent nursing diagnosis for this patient is acute pain (Choice C). This is because the patient's right femur fracture would likely cause significant pain and discomfort, which is a priority to address for optimal recovery and comfort. Managing pain effectively is crucial in promoting healing and preventing complications. Posttrauma syndrome (Choice A) is not as immediate a concern in this scenario. While constipation (Choice B) and anxiety (Choice D) are important considerations, addressing acute pain takes precedence in the initial plan of care to ensure the patient's comfort and well-being.

Correct Answer: B

Rationale: The correct answer is B: 7th cranial nerve. Bell's palsy is caused by inflammation of the facial nerve (7th cranial nerve), leading to facial muscle weakness or paralysis. The 3rd cranial nerve (choice A) controls eye movement, the 5th cranial nerve (choice C) is responsible for facial sensation and chewing, and the 8th cranial nerve (choice D) is related to hearing and balance. Bell's palsy specifically affects the facial muscles, making choice B the correct answer.

Correct Answer: D

Rationale: The correct answer is D. In bronchiectasis, worsening cough with position changes is an assessment finding due to increased sputum production and airway obstruction. This occurs because of the pooling of secretions in the affected bronchi. Choices A, B, and C are incorrect because in bronchiectasis, there is typically increased sputum production over time, productive cough with expectoration of large amounts of sputum, and cough that worsens with activity or physical exertion, rather than with position changes.

Correct Answer: B

Rationale: The correct answer is B because it follows the SMART approach: Specific (monitor heart rhythm), Measurable (continuously this shift), Achievable (feed self at all mealtimes), Relevant (shortness of breath), and Time-bound (today). Choice A lacks specificity and measurability. Choice C focuses on the nurse's action, not patient outcomes. Choice D lacks specificity and measurability, focusing on the nurse's actions rather than patient outcomes.

Correct Answer: D

Rationale: The correct answer is D: To determine clients response to therapy. Evaluating BUN, creatinine, and serum electrolyte levels in a client being treated for acute pyelonephritis helps the nurse assess the effectiveness of the therapy. Changes in these levels indicate how well the kidneys are functioning and how the client is responding to treatment. Monitoring these parameters allows for adjustments in therapy if needed. Incorrect choices: A: To determine the severity of the disorder - While these tests can provide information about the severity of kidney dysfunction, the primary focus is on monitoring the response to therapy. B: To identify signs of fluid retention - While BUN and creatinine levels can indirectly indicate fluid status, the main purpose of evaluating these tests is to assess therapy response. C: To determine the location of discomfort - These tests do not provide information about the location of discomfort but rather focus on kidney function and response to treatment.
