A nurse is educating a patient who has been prescribed an antidepressant for depression. Which of the following is the most appropriate information for the nurse to provide?

Strong or aged cheese should not be eaten while taking them

Its full therapeutic potential may not be reached until 4-6 weeks

They should not be given with antianxiety agents

It may cause hypomania, weight gain, and an increase in sleep

Answer and Explanation

The Correct Answer is B

Choice A reason: Avoiding strong or aged cheese applies to MAOIs due to tyramine interactions causing hypertensive crises. Most antidepressants, like SSRIs or SNRIs, do not require this dietary restriction, as they do not affect monoamine oxidase, making this information incorrect.

Choice B reason: Antidepressants, such as SSRIs, typically require 4-6 weeks to achieve full therapeutic effects by increasing neurotransmitter levels (serotonin, norepinephrine) in the brain. This delay is critical for patient expectations and adherence, making this the most appropriate information to provide.

Choice C reason: Antidepressants can be safely combined with antianxiety agents, such as benzodiazepines, under medical supervision for co-occurring anxiety and depression. This statement is incorrect, as combination therapy is common and does not require avoidance, depending on the clinical context.

Choice D reason: Hypomania, weight gain, and increased sleep are possible side effects of some antidepressants (e.g., mirtazapine), but they are not universal. SSRIs may cause insomnia or weight loss, making this information less broadly applicable than the therapeutic delay information.

Correct Answer is ["1.44"]

Explanation

Step 1: Calculate the total units to be given per hour: 18 × 90 = 1620 units/hour Result = 1620 units/hour

Step 2: Determine the concentration of Heparin in 1 mL: 25000 ÷ 250 = 100 units/mL Result = 100 units/mL

Step 3: Calculate the required volume in mL/hr using total units per hour: (1620 ÷ 100) = 16.2 mL/hr Result = 16.2 mL/hr

Final answer 16.2 mL/hr

Question 47

Calculate the initial bolus of Heparin. Heparin is ordered as 80 units/kg. The client weighs 90 kg. How many mL would you administer using a vial of Heparin labeled Heparin 5000 units/mL?

The correct answer is 1.44 mL

Explanation:

Step 1: Calculate the total number of units required for the bolus: 80 × 90 = 7200 units Result = 7200 units

Step 2: Use the vial concentration to find out how many mL deliver 7200 units: (7200 ÷ 5000) = 1.44 mL Result = 1.44 mL

Final answer 1.44 mL

A. The potential for dependence and tolerance B. It should be taken first thing in the morning with food C. The importance of discontinuing immediately if addiction is suspected D. Increased caffeine consumption will increase the effectiveness

Correct Answer is A

Explanation

Choice A reason: Benzodiazepines enhance GABA activity, leading to rapid anxiety relief but with a high risk of tolerance and dependence. Teaching about this risk is critical to ensure the client understands the need for medical supervision, potential withdrawal symptoms, and strategies to prevent misuse or long-term dependency.

Choice B reason: Taking benzodiazepines with food may reduce gastrointestinal upset, but the timing is not critical for efficacy. This instruction is less urgent than addressing dependence, as benzodiazepines are effective regardless of meal timing, and the primary concern is their addictive potential.

Choice C reason: Discontinuing benzodiazepines abruptly can cause severe withdrawal symptoms, including seizures, due to their effect on GABA receptors. This is dangerous advice, as gradual tapering under medical supervision is required, making this choice incorrect and less critical than teaching about dependence risks.

Choice D reason: Increased caffeine consumption can counteract benzodiazepine effects by stimulating the central nervous system, potentially worsening anxiety. This is incorrect advice, as it could reduce the medication’s efficacy and exacerbate symptoms, making it less relevant than educating about dependence and tolerance risks.
