Correct Answer: A

Rationale: Healthcare professionals should perform hand hygiene before and after patient contact to prevent the spread of infections. While choices B, C, and D are also important times to practice hand hygiene, they are not as crucial as before and after patient contact because patient contact poses a higher risk of transmitting infections.

Correct Answer: C

Rationale: Asking about alcohol intake is crucial in assessing the client's risk factors and behaviors, especially in the context of a suicide threat. Understanding alcohol consumption patterns can help the nurse evaluate potential substance abuse issues and their impact on the client's mental health. Choices A, B, and D are less pertinent to the immediate concern of assessing suicide risk and conduct disorder symptoms.

Correct Answer: A

Rationale: The correct answer is to administer calcium gluconate. In hyperkalemia, the priority is to protect the heart from potential complications like arrhythmias. Calcium gluconate is the first-line treatment as it stabilizes the cardiac cell membrane. Insulin (Choice B) and sodium bicarbonate (Choice C) can be used in conjunction with other treatments to shift potassium into cells, but calcium gluconate is the priority. Administering a diuretic (Choice D) is not the primary intervention for hyperkalemia and can even worsen the condition by reducing potassium excretion.

Correct Answer: D

Rationale: The correct answer is D because viewing the newborn's actions as uncooperative indicates a lack of bonding, which requires intervention. Choices A, B, and C all involve appropriate and caring actions by the client towards the newborn. Holding the newborn in an en face position promotes bonding, involving the father in caring for the newborn is beneficial for family involvement, and requesting rest by asking the nurse to take the newborn to the nursery is a responsible action to ensure both the client and the newborn get adequate rest.
