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
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 B
Explanation
A nurse who is caring for a preschooler should question a prescription for tetracycline. Tetracycline is contraindicated in children under 8 years of age due to its potential to cause permanent discoloration and damage to developing teeth and bones. This adverse effect is known as tooth staining or dental hypoplasia.
Let's go through the other options:
A. Azithromycin: Azithromycin is an appropriate antibiotic for use in preschool-age children and is commonly prescribed for various bacterial infections. It does not pose the same risk of tooth staining as tetracycline, making it a safe option for this age group.
C. Cefuroxime: Cefuroxime is another antibiotic that is safe for use in preschoolers. It belongs to the cephalosporin class of antibiotics and is commonly prescribed for respiratory tract infections, skin infections, and other bacterial infections.
D. Gentamicin: While gentamicin is an effective antibiotic, its use in preschool-age children should be carefully monitored. Gentamicin can have potential ototoxic and nephrotoxic effects (damage to the inner ear and kidneys, respectively). However, its use is not strictly contraindicated in this age group, and it can be prescribed when necessary with appropriate monitoring.
Correct Answer is B
Explanation
When caring for a client receiving a continuous infusion of total parenteral nutrition (TPN), the nurse should implement the intervention of checking the client's blood glucose level regularly. TPN is a highly concentrated intravenous nutrition solution containing glucose, amino acids, lipids, vitamins, and minerals, and it is used to provide complete nutrition when the client cannot take oral nutrition.
Monitoring blood glucose levels regularly is essential because TPN is rich in glucose, which can significantly affect the client's blood sugar levels. Hyperglycemia (high blood sugar) is a potential complication of TPN infusion. Regular blood glucose monitoring allows the nurse to detect and address any changes in blood sugar levels promptly and to adjust the TPN infusion rate or administer insulin, if necessary, to maintain the client's blood sugar within the target range.
Let's go through the other options:
A. Change the TPN infusion tubing once every 3 days: While changing the TPN infusion tubing regularly is a good practice to maintain asepsis and prevent infection, it is not the priority intervention in this situation. Regularly checking the client's blood glucose level is more crucial to monitor the effects of TPN on blood sugar levels.
C. Insert the peripheral IV catheter for administration: Total parenteral nutrition is a hypertonic solution that can cause irritation and damage to peripheral veins. It is usually administered through a central venous catheter (CVC) placed in a large vein, such as the subclavian or jugular vein. Inserting a peripheral IV catheter for TPN administration is not recommended due to the risk of vein damage and thrombosis.
D. Monitor the client's weight every 3 days: Monitoring the client's weight is an important part of assessing their nutritional status and fluid balance. However, the priority intervention for a client receiving TPN is checking their blood glucose level regularly, as hyperglycemia is a common and significant concern in TPN administration.
