Correct Answer: A

Rationale: The correct answer is that the patient is in the late stage of dementia. In late-stage dementia, individuals may have an inability to follow commands and understand instructions independently, which are essential for proper installation and use of a CPAP machine. This makes using a CPAP machine challenging and potentially ineffective for patients in this condition. Choice B, having a history of bronchitis, does not contraindicate the use of a CPAP machine. In fact, CPAP therapy can be beneficial for patients with respiratory conditions like bronchitis. Choice C, a history of suicidal gestures/attempts, while concerning for the patient's mental health, does not directly contraindicate the use of a CPAP machine. Choice D, being on beta-blockers, is not a contraindication for CPAP machine use. Beta-blockers are commonly used medications for various conditions and do not interfere with the use of a CPAP machine.

Correct Answer: D

Rationale: The correct answer is 'No measurable voiding in 4 hours.' This finding should be reported to the healthcare provider immediately. The concern is the possibility of hyperkalemia, which could occur with continued potassium administration and a decrease in urinary output since potassium is excreted via the kidneys. It is crucial to monitor urinary output in pediatric patients receiving potassium-containing IV solutions to prevent electrolyte imbalances and potential complications. Choices A, B, and C are not the most critical findings that require immediate reporting. '3 episodes of vomiting in 1 hour' may suggest a need for antiemetic therapy or further assessment of the underlying cause but does not pose an immediate risk like the potential electrolyte imbalance from decreased urinary output. 'Periodic crying and irritability' and 'Vigorous sucking on a pacifier' are common behaviors in infants and are not indicative of a critical condition that requires urgent attention in this scenario.

Correct Answer: B

Rationale: When a newborn is placed in a warming isolette due to difficulty maintaining temperature, the priority action is to continuously monitor the neonate's temperature to prevent overheating. Using heat lamps is unsafe as their temperature cannot be regulated, potentially causing harm. Warming medications and fluids before administration is not necessary in this situation. While touching the neonate with cold hands may startle them, it does not pose a safety risk compared to monitoring and controlling the temperature.

Correct Answer: D

Rationale: A temperature of 102.5°F or higher following immunization is considered an adverse reaction and should be reported immediately. This could indicate a more serious systemic response to the vaccine. Irritability, slight edema at the injection site, and local tenderness are common, mild side effects of routine immunizations and do not typically require immediate reporting. Other reactions that should be reported immediately include excessive crying for more than 3 hours, seizure activity, and the presence of tender, swollen, or reddened areas at the injection site.

Correct Answer: C

Rationale: The correct answer is the working phase. During this phase, the nurse and client actively work together to explore alternative behaviors and techniques. Discussions in this phase focus on understanding the underlying meaning behind the behavior and implementing strategies for change. Pre-interaction (choice A) refers to the phase before the nurse and client first meet and establish a relationship. The orientation phase (choice B) involves introductions, setting goals, and establishing boundaries. Termination (choice D) is the phase where the therapeutic relationship concludes, and closure is achieved.
