A nurse is providing teaching for a client who has a new prescription for promethazine tablets. Which of the following client statements indicates an understanding of the teaching?

"This medication can cause diarrhea

"The medication can cause increased salivation

"This medication can cause pupil constriction"

"The medication can cause drowsiness

Answer and Explanation

The Correct Answer is D

The client statement that indicates an understanding of the teaching is: "The medication can cause drowsiness."

Promethazine is an antihistamine medication commonly used to treat various conditions, such as allergies, motion sickness, and nausea. One of the most common side effects of promethazine is drowsiness or sedation. It has a significant sedative effect, and it is often used to induce sleep or manage insomnia in some cases.

Let's go through the other options:

A. "This medication can cause diarrhea": Diarrhea is not a common side effect of promethazine. While promethazine can cause certain gastrointestinal side effects like constipation or upset stomach, diarrhea is not typically associated with its use.

B. "The medication can cause increased salivation": Increased salivation is not a common side effect of promethazine. While some antihistamines can cause dry mouth, which is the opposite of increased salivation, promethazine does not usually cause excessive salivation.

C. "This medication can cause pupil constriction": Pupil constriction (miosis) is a potential side effect of some medications, but it is not commonly associated with promethazine. Promethazine is more likely to cause pupil dilation (mydriasis) rather than constriction.

Correct Answer is C

Explanation

A. Hemoglobin level: The hemoglobin level measures the amount of hemoglobin, the oxygen-carrying protein in red blood cells, in the blood. Warfarin is not directly responsible for increasing or decreasing the hemoglobin level. While warfarin can lead to bleeding complications in some cases, it does not specifically target the hemoglobin level, so it is not a direct indicator of the medication's effectiveness.

B. Platelet count: The platelet count measures the number of platelets in the blood, which are essential for blood clotting. Warfarin does not directly affect platelet production or count. It works by inhibiting the production of certain clotting factors, not by affecting platelets. Monitoring the platelet count is important, but it is not an indicator of warfarin's effectiveness in preventing excessive clotting.

C. Prothrombin time (PT) or activated partial thromboplastin time (aPTT): Prothrombin time (PT) and activated partial thromboplastin time (aPTT) are coagulation tests used to assess different types of anticoagulant medications, such as heparin. Warfarin's effect is measured using the International Normalized Ratio (INR). PT and aPTT are not specific to warfarin therapy and are not used to monitor its effectiveness. The INR is the appropriate laboratory test for assessing the efficacy of warfarin therapy.

D. International Normalized Ratio (INR): This is the correct answer. The International Normalized Ratio (INR) is the laboratory test used to monitor the effectiveness of warfarin therapy. The INR measures the time it takes for the blood to clot and reflects the anticoagulant effect of warfarin. A therapeutic INR within the target range (e.g., INR = 2.0 to 3.0 for most indications) indicates that warfarin has been effective in preventing excessive clotting and reducing the risk of complications associated with blood clots.

A. Thyroid-stimulating hormone B. Hemoglobin C. Blood glucose D. Alanine aminotransferase E. Iron

Correct Answer is ["B","E"]

Explanation

The nurse should monitor the following laboratory tests to determine the effectiveness of epoetin alfa:

B. Hemoglobin: Epoetin alfa is a medication used to treat anemia by stimulating red blood cell production. Monitoring hemoglobin levels can help assess if the medication is effectively increasing red blood cell production and improving anemia.

E. Iron: Iron is essential for red blood cell production. Monitoring iron levels can help determine if the client has adequate iron stores to support the increased production of red blood cells stimulated by epoetin alfa.

The other options listed, A. Thyroid-stimulating hormone, C. Blood glucose, and D. Alanine aminotransferase, are not directly related to the effectiveness of epoetin alfa in treating anemia. Thyroid-stimulating hormone is related to thyroid function, blood glucose is related to blood sugar control, and alanine aminotransferase is related to liver function. While these tests may be important for monitoring the overall health of the client, they are not specific indicators of the effectiveness of epoetin alfa.
