The client receives one dose of 200 mg of a medication. How much drug is in the body at 3 half-lives?

100

Answer and Explanation

The Correct Answer is C

Here’s the step-by-step process:

After the first half-life (1 half-life), 50% of the initial drug is left.

200 mg → 100 mg (half is eliminated, 100 mg remains).

After the second half-life (2 half-lives), 50% of the remaining drug is eliminated again.

100 mg → 50 mg (half of 100 mg is eliminated, 50 mg remains).

After the third half-life (3 half-lives), 50% of the remaining drug is eliminated again.

50 mg → 25 mg (half of 50 mg is eliminated, 25 mg remains).

Correct Answer is A

Explanation

A) 1 x soft bowel movement: This is the correct answer. Psyllium is a bulk-forming laxative that helps to relieve constipation by absorbing water into the stool, making it easier to pass. A therapeutic effect of psyllium would be the client experiencing a soft bowel movement, indicating the medication has helped to regulate the client's bowel movements and relieve constipation.

B) Gastric pH 2 (Normal pH: 1-4): While this is a normal gastric pH range, it is not related to the therapeutic effect of psyllium. Psyllium works in the gastrointestinal tract to promote bowel regularity, not to alter gastric pH. The pH measurement of gastric contents is not a relevant indicator of the medication's effectiveness.

C) 500 ml of urine output: This finding is not related to the therapeutic effect of psyllium. Psyllium is intended to address bowel function, not urine output. Adequate urine output should be monitored, but it is not the expected outcome for a patient taking psyllium.

D) Blood glucose: 95 (Normal Fasting Blood Glucose: 60-120): While a normal blood glucose level is important, it is not relevant to the action of psyllium. Psyllium does not have a direct effect on blood glucose levels, so a normal blood glucose result is not indicative of a therapeutic effect of the medication.

A. Problems that cause severe discomfort to the client B. Problems the client deems most important C. Problems that are immediately life-threatening for the client D. Problems that are identified as priority by the physician

Correct Answer is C

Explanation

A) Problems that cause severe discomfort to the client: While addressing discomfort is important in providing holistic care, it is not the highest priority in nursing. The nurse’s primary focus should be on life-threatening issues or those that could deteriorate the client’s condition rapidly. Severe discomfort can be managed once immediate threats to life are addressed.

B) Problems the client deems most important: Although it’s essential to consider the client’s perspective and involve them in their care plan, problems that are most important to the client may not always be the most urgent or life-threatening. For example, the client may prioritize pain management, but addressing life-threatening issues must always take precedence.

C) Problems that are immediately life-threatening for the client: This is the correct answer. According to Maslow’s hierarchy of needs and the nursing prioritization framework, life-threatening problems should always be the nurse's first priority. These are issues that, if not addressed immediately, can lead to death or severe complications. For instance, airway obstruction, severe bleeding, or shock would require immediate intervention.

D) Problems that are identified as priority by the physician: While the physician’s orders and priorities should be taken into consideration, the nurse must independently assess and prioritize care based on the overall health status of the client. This includes using clinical judgment to identify life-threatening conditions, even if they are not explicitly stated in the physician’s orders. Nurses are trained to identify priority issues through their assessments and are responsible for making decisions that ensure the client’s safety.
