A nurse is providing teaching to a client who has angina and a new prescription for nitroglycerin tablets. Which of the following instructions should the nurse include in the teaching?

A.

Repeat up to four doses until pain is relieved.

B.

Store unused tablets at room temperature.

C.

Take two tablets at the onset of pain.

D.

Take the medication two hours prior to exercise.

Answer and Explanation

The Correct Answer is B

Choice A rationale

 

Repeating up to four doses until pain is relieved is incorrect. The correct instruction is to take one tablet at the onset of pain and repeat every 5 minutes if needed, up to a maximum of three tablets in 15 minutes.

 

Choice B rationale

 

Storing unused tablets at room temperature is correct. Nitroglycerin tablets should be stored in their original container at room temperature, away from moisture and heat.

 

Choice C rationale

 

Taking two tablets at the onset of pain is incorrect. The correct instruction is to take one tablet at the onset of pain and repeat every 5 minutes if needed, up to a maximum of three tablets in 15 minutes.

 

Choice D rationale

 

Taking the medication two hours prior to exercise is incorrect. Nitroglycerin should be taken 5 to 10 minutes before an activity that may cause chest pain.

Correct Answer is E

Explanation

Choice A rationale

Hypercalcemia is not typically a risk in the emergency department unless the patient has a specific condition that causes elevated calcium levels.

Choice B rationale

Hypotension can occur in the emergency department, especially in cases of shock or severe dehydration, but it is not the most common risk.

Choice C rationale

Hypokalemia can occur, particularly in patients with certain medical conditions or those taking diuretics, but it is not the most common risk.

Choice D rationale

Hypernatremia can occur, especially in patients with dehydration or certain medical conditions, but it is not the most common risk.

Choice E rationale

Hypoglycemia is a common risk in the emergency department, especially in patients with diabetes or those who have not eaten for an extended period.

Correct Answer is A

Explanation

Choice A rationale

Elevated alanine aminotransferase (ALT) is an adverse effect of simvastatin therapy. Statins, including simvastatin, can cause liver damage, which is indicated by elevated liver enzymes such as ALT2.

Choice B rationale

Elevated troponin T is not typically associated with simvastatin therapy. Troponin T is a marker for cardiac muscle damage, not a common adverse effect of statins.

Choice C rationale

Elevated WBC count is not a known adverse effect of simvastatin therapy. An elevated WBC count usually indicates an infection or inflammation.

Choice D rationale

Elevated thyroid-stimulating hormone (TSH) is not associated with simvastatin therapy. TSH levels are related to thyroid function, not the effects of statins.
