Protect the skin from sunlight while taking the drug.

Take with orange juice to enhance GI absorption.

Return to the clinic weekly to obtain serum drug levels.

Take with milk or antacids to prevent gastrointestinal (GI) irritation.

Answer and Explanation

The Correct Answer is A

Choice A reason: Tetracycline HCl can cause photosensitivity, which increases the risk of sunburn and skin damage. The client should avoid direct sunlight and use sunscreen and protective clothing while taking the drug.

Choice B reason: Orange juice is acidic and can decrease the absorption of tetracycline HCl. The client should take the drug with water and avoid acidic foods and beverages.

Choice C reason: Serum drug levels are not routinely monitored for tetracycline HCl. The client should follow the prescribed dosage and duration of the therapy.

Choice D reason: Milk and antacids can interfere with the absorption of tetracycline HCl. The client should take the drug at least 1 hour before or 2 hours after meals and avoid dairy products and antacids.

Correct Answer is C

Explanation

Choice A reason: This is not the laboratory finding that indicates that the medication has been effective. Serum ammonia level of 30 Mcg/dL (17.62 mmol/L) is within the normal range for adults, and it does not reflect the effect of sodium polystyrene sulfonate. Sodium polystyrene sulfonate is a cation-exchange resin that binds to potassium in the intestine and removes it from the body through the stool. It does not affect the ammonia levels in the blood, which are influenced by the liver function and the urea cycle. The nurse should monitor the ammonia levels for any changes, but it is not the goal of the medication.

Choice B reason: This is not the laboratory finding that indicates that the medication has been effective. Hemoglobin level of 13.5 g/dL (135 g/L) is within the normal range for females, and it does not reflect the effect of sodium polystyrene sulfonate. Sodium polystyrene sulfonate does not affect the hemoglobin levels in the blood, which are determined by the number and size of red blood cells and the oxygen-carrying capacity of the blood. The nurse should monitor the hemoglobin levels for any changes, but it is not the goal of the medication.

Choice C reason: This is the laboratory finding that indicates that the medication has been effective. Serum potassium level of 3.8 mEq/L (3.8 mmol/L) is within the normal range for adults, and it indicates that the medication has lowered the potassium levels in the blood. Sodium polystyrene sulfonate is used to treat hyperkalemia, or high potassium levels, which can occur in AKI due to the impaired renal excretion of potassium. Hyperkalemia can cause cardiac arrhythmias, muscle weakness, and paralysis. The nurse should administer sodium polystyrene sulfonate as prescribed and check the serum potassium levels regularly to ensure that they are within the normal range.

Choice D reason: This is not the laboratory finding that indicates that the medication has been effective. Serum glucose level of 120 mg/dL (6.7 mmol/L) is slightly above the normal range for adults, and it does not reflect the effect of sodium polystyrene sulfonate. Sodium polystyrene sulfonate does not affect the glucose levels in the blood, which are influenced by the carbohydrate metabolism and the insulin secretion and action. The nurse should monitor the glucose levels for any changes, but it is not the goal of the medication.

A. Ginkgo biloba use should be limited and not taken during pregnancy. B. Aspirin and non-steroidal anti-inflammatory drugs interact with ginkgo. C. Nausea and diarrhea can occur when using this supplement. D. Anxiety and headaches increase with the use of ginkgo biloba.

Correct Answer is B

Explanation

Choice A reason: Ginkgo biloba use should be limited and not taken during pregnancy is a true statement, but not the most important information for the nurse to include in the teaching plan. Ginkgo biloba may have adverse effects on the fetus, such as bleeding, seizures, or malformations. However, this information is only relevant if the client is pregnant or planning to become pregnant. The nurse should assess the client's reproductive status and advise her accordingly.

Choice B reason: Aspirin and non-steroidal anti-inflammatory drugs interact with ginkgo is the most important information for the nurse to include in the teaching plan. Ginkgo biloba has antiplatelet and anticoagulant properties, which means it can prevent blood clots from forming. However, this also increases the risk of bleeding, especially when combined with other drugs that affect blood clotting, such as aspirin and non-steroidal anti-inflammatory drugs (NSAIDs). The nurse should instruct the client to avoid taking these drugs with ginkgo biloba and inform the healthcare provider of all the medications and supplements she is using.

Choice C reason: Nausea and diarrhea can occur when using this supplement is a possible side effect of ginkgo biloba, but not the most important information for the nurse to include in the teaching plan. Nausea and diarrhea are usually mild and transient, and can be reduced by taking ginkgo biloba with food or water. The nurse should inform the client of this possibility and advise her to report any severe or persistent symptoms to the healthcare provider.

Choice D reason: Anxiety and headaches increase with the use of ginkgo biloba is a false statement, and not the information for the nurse to include in the teaching plan. Ginkgo biloba may actually have beneficial effects on anxiety and headaches, as it can improve blood circulation and oxygen delivery to the brain. The nurse should not discourage the client from using ginkgo biloba for these reasons, unless there is a contraindication or an interaction with other drugs.
