A young adult female client who is planning to become pregnant asks the nurse if she can continue taking isotretinoin for cystic acne. Which information is most important for

the nurse to provide this client?

Breast feeding is not recommended while taking this medication.

Baseline liver function results must be obtained during therapy.

Do not take multiple vitamins that contain vitamin A while taking this drug.

Answer and Explanation

The Correct Answer is D

Choice A reason: Breast feeding is not recommended while taking this medication, as isotretinoin can pass into breast milk and harm

the nursing infant. However, this information is not as important as choice d, as the client may not be breast feeding or planning to breast feed.

Choice B reason: Baseline liver function results must be obtained during therapy, as isotretinoin can cause liver damage and increase liver enzymes. However, this information is not as important as choice d, as the client may not have liver problems or need liver function tests.

Choice C reason: Do not take multiple vitamins that contain vitamin A while taking this drug, as isotretinoin is a derivative of vitamin A and can cause vitamin A toxicity if taken in excess. However, this information is not as important as choice d, as the client may not take multiple vitamins or have vitamin A toxicity.

Choice D reason: Discontinue this medication one month before attempting to conceive, as isotretinoin can cause severe birth defects and miscarriages if taken during pregnancy. Therefore, this information is most important for the nurse to provide this client, as the client is planning to become pregnant and should avoid isotretinoin exposure.

Correct Answer is C

Explanation

Choice C reason: Sodium polystyrene sulfonate is a cation-exchange resin that binds to potassium in the intestine and removes it from the body through the stool. Sodium polystyrene sulfonate is used to treat hyperkalemia, or high potassium level, which can be caused by AKI, certain medications, or other conditions. Hyperkalemia can cause cardiac arrhythmias, muscle weakness, paralysis, or death. The normal range of potassium for adults is 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L). Therefore, a decrease in potassium from above normal to within normal indicates that sodium polystyrene sulfonate has been effective in lowering potassium level and preventing complications. The nurse should monitor the client's serum potassium level regularly and adjust the dose of sodium polystyrene sulfonate as needed.

Choice A reason: Hemoglobin level of 13.5 g/dL (135 g/L) is not a laboratory finding that indicates that the medication has been effective, but rather a normal value that reflects the amount of oxygen-carrying protein in the blood. Hemoglobin is not affected by sodium polystyrene sulfonate or potassium level. The normal range of hemoglobin for adults is 12 to 16 g/dL (120 to 160 g/L). Therefore, a hemoglobin level of 13.5 g/dL does not indicate any change or improvement in the client's condition.

Choice B reason: Serum glucose level of 120 mg/dL (6.7 mmol/L) is not a laboratory finding that indicates that the medication has been effective, but rather a slightly elevated value that reflects the amount of sugar in the blood. Glucose is not affected by sodium polystyrene sulfonate or potassium level. The normal range of glucose for adults is 74 to 106 mg/dL (4.1 to 5.9 mmol/L). Therefore, a serum glucose level of 120 mg/dL may indicate impaired glucose metabolism or diabetes mellitus, but not the effectiveness of sodium polystyrene sulfonate.

Choice D reason: Serum ammonia level of 30 mg/dL (17.62 µmol/L) is not a laboratory finding that indicates that the medication has been effective, but rather a normal value that reflects the amount of nitrogen waste in the blood. Ammonia is not affected by sodium polystyrene sulfonate or potassium level. The normal range of ammonia for adults is 10 to 80 mg/dL (6 to 47 µmol/L). Therefore, a serum ammonia level of 30 mg/dL does not indicate any change or improvement in the client's condition.

Correct Answer is ["42"]

Explanation

The correct answer is 42gtt/min.

To calculate the infusion rate, use the formula:

gtt/min = (volume in mL x drop factor in gtt/mL) / time in min

Plug in the given values:

gtt/min = (500 mL x 10 gtt/mL) / 120 min

gtt/min = 5000 gtt / 120 min

gtt/min = 41.67 gtt/min

Round to the nearest whole number:

gtt/min = 42 gtt/min
