A nurse is providing preoperative teaching to a client about the administration of morphine via a PCA pump.
Which of the following statements by the client indicates an understanding of the teaching?

"Using this machine increases my risk of overdose."

"I can get pain medication any time as long as I press the button."

"My partner can press my pain medication button for me if I am sleeping."

"I will receive a limited amount of pain medication when I press the button." .

Answer and Explanation

The Correct Answer is D

The correct answer is D.

Choice A reason: “A. Using this machine increases my risk of overdose.” This statement is incorrect because PCA pumps are designed with safety mechanisms to prevent overdose. The pump is programmed to deliver a specific dose of medication at set intervals, and it will not dispense more medication than what is prescribed by the healthcare provider.

Choice B reason: “B. I can get pain medication any time as long as I press the button.” While it is true that the patient can self-administer medication, PCA pumps have a lockout interval that prevents the machine from delivering another dose until a certain amount of time has passed, ensuring that the patient cannot receive medication too frequently.

Choice C reason: “C. My partner can press my pain medication button for me if I am sleeping.” This statement is incorrect. Only the patient should press the button on the PCA pump to ensure that the medication is administered safely and according to the patient’s current level of pain. Allowing someone else to press the button could lead to unsafe dosing.

Choice D reason: “D. I will receive a limited amount of pain medication when I press the button.” This is the correct statement. The PCA pump allows the patient to administer a controlled amount of pain medication within safe limits set by the healthcare provider. The pump is programmed to deliver a specific dose of medication, and there is a limit to the number of doses that can be administered per hour.

Correct Answer is B

Explanation

The correct answer is B. The nurse should encourage the family to express their feelings of loss and provide emotional support and comfort during this difficult time. The nurse should also respect their cultural and religious beliefs and practices regarding death and dying, and allow them to spend as much time as they need with their loved one's body, unless there are infection control issues or legal requirements that prevent it. The other options are incorrect because they are insensitive and disrespectful to the family's needs and wishes.

A. Acetone breath. B. Confusion. C. Polydipsia. D. Hot, dry skin.

Correct Answer is B

Explanation

Choice A rationale:

Acetone breath is a symptom of diabetic ketoacidosis (DKA), a complication of diabetes mellitus. It occurs due to the presence of ketones in the breath and is not specific to hypoglycemia. Hypoglycemia is characterized by low blood sugar levels, not elevated ketone levels.

Choice B rationale:

Confusion is a common symptom of hypoglycemia. When blood sugar levels drop significantly, the brain may not receive enough glucose to function properly, leading to confusion, dizziness, and other neurological symptoms.

Choice C rationale:

Polydipsia refers to excessive thirst and is a symptom of hyperglycemia (high blood sugar levels), not hypoglycemia. In hyperglycemic states, the body tries to eliminate excess glucose through urine, leading to increased thirst.

Choice D rationale:

Hot, dry skin is not a typical symptom of hypoglycemia. Hypoglycemia can cause diaphoresis (excessive sweating) and cool, clammy skin due to the body's stress response.
