Correct Answer: B

Rationale: The correct answer is to use a 20 ml syringe to deflate the balloon first when removing a suprapubic catheter. This step is essential to ensure the safe removal of the catheter without causing any harm or discomfort to the client. Deflating the balloon allows for the catheter to be easily removed. Option A, cleansing the site around the catheter, is not the initial step in this process and can be done after catheter removal. Option C, clamping the catheter until the client voids naturally, is incorrect as it can lead to complications like urinary retention. Option D, emptying urine from the urinary drainage bag, is not the first step in removing the suprapubic catheter and does not address the need to deflate the balloon for safe removal.

Correct Answer: B

Rationale: The correct answer is B. A biophysical profile score of 5 out of 8 indicates potential fetal distress, necessitating immediate assessment to ensure the well-being of the fetus. The other options, while important, do not suggest an immediate threat to the fetus' health. The 38-week primigravida with contractions every 10 minutes may be in early labor, the 41-week multigravida scheduled for induction can be assessed after addressing the immediate concern, and the 36-week multigravida with serial blood pressure can be assessed after ensuring the client with potential fetal distress is stabilized.

Correct Answer: C

Rationale: The correct action for the nurse to take when a pregnant woman is choking and unable to speak is to perform the Heimlich maneuver using subdiaphragmatic thrusts. This technique is recommended for a pregnant woman to prevent harm to the fetus. Option A, cardiopulmonary resuscitation with uterine tilt, is not indicated for a choking episode. Option B, the Heimlich maneuver using chest thrusts, can potentially harm the gravid uterus. Option D, calling 911 immediately before providing assistance, can lead to a delay in addressing the immediate choking emergency.

Correct Answer: B

Rationale: The correct first action for a newborn potentially exposed to HIV is to bathe the infant with dilute chlorhexidine or soap. This helps reduce the risk of infection. Initiating treatment with zidovudine would be important but not the first priority. Measuring and recording the infant's frontal-occipital circumference and administering vitamin K are important tasks but are not the priority when dealing with potential HIV exposure. Immediate hygiene measures are crucial to minimize the risk of transmission.

Correct Answer: B

Rationale: In the scenario described, the nurse notes late decelerations during contractions despite repositioning and oxygen administration. Late decelerations are often associated with uteroplacental insufficiency, which can be exacerbated by increased uterine activity stimulated by oxytocin. The initial action to manage late decelerations is to turn off the oxytocin infusion to reduce uterine stimulation. This step aims to improve fetal oxygenation and prevent further stress on the fetus. Immediate cesarean birth may be necessary if the late decelerations persist or worsen despite discontinuing the oxytocin infusion. Notifying the anesthesiologist to disconnect the epidural infusion or applying an internal fetal monitoring device are not the first-line interventions for managing late decelerations.
