Correct Answer: B

Rationale: The correct action for the nurse to assist the client who is experiencing difficulty voiding after the removal of an indwelling catheter is to pour warm water over the perineum. This technique can help stimulate urination by promoting relaxation of the perineal muscles and improving blood flow to the area. Assessing for bladder distention after 4 hours (Choice A) is important but not the immediate intervention needed to assist the client in voiding. Restricting the client's oral fluid intake (Choice C) can exacerbate the issue by reducing urine production. Restricting movement for at least 12 hours (Choice D) is unnecessary and may lead to discomfort and other complications.

Correct Answer: A

Rationale: The correct answer is A: Fever, chills, and increased heart rate are classic signs of an infection. These symptoms indicate the body's response to an invading pathogen. Choice B, 'Increased white blood cell count and fever,' is not a primary symptom that a person would typically notice themselves, and white blood cell count needs to be tested. Choice C, 'Shortness of breath and confusion,' may indicate other conditions like heart or lung issues rather than a general infection. Choice D, 'Sweating and low blood pressure,' are not specific to infections and can be caused by various factors like heat or dehydration.

Correct Answer: A

Rationale: The correct answer is A. Positive urine glucose and acetone could indicate gestational diabetes or preeclampsia, both of which are complications. Choice B, pedal edema, is common in pregnancy but may also be a sign of preeclampsia if severe. Choice C, an increase in vaginal discharge, is a normal finding in pregnancy due to hormonal changes. Choice D, pressure against the diaphragm when the baby moves, is a normal sensation due to the growing uterus displacing abdominal contents.

Correct Answer: A

Rationale: To assess a patient for potential deep vein thrombosis (DVT), healthcare professionals should look for unilateral leg swelling. This is a classic sign of DVT. While encouraging early mobilization is generally beneficial for preventing DVT, it is not a method of assessment. Checking for calf tenderness is also relevant but not as specific as unilateral leg swelling. Observing for redness and warmth can be signs of inflammation but are not as specific to DVT as unilateral leg swelling.

Correct Answer: D

Rationale: Pupil accommodation problems are indicated by the lack of change in size when shifting gaze from far to near. The correct answer is D because in pupil accommodation, the pupils should constrict when shifting gaze from far to near in order to adjust for near vision. Choices A and B describe normal responses of pupil constriction when shifting gaze, which do not indicate a problem. Choice C is incorrect as it describes a normal response of pupil size change when shifting gaze from near to far.
