A nurse is teaching a class about using niacin to reduce LDL cholesterol.
The nurse should include in the teaching that which of the following conditions is a contraindication for receiving this medication?

Hyperthyroidism.

Asthma.

High blood pressure.

Active liver disease.

Answer and Explanation

The Correct Answer is D

Choice A rationale:

Hyperthyroidism is not a contraindication for niacin use. Niacin is used to lower LDL cholesterol levels and has no specific contraindications related to thyroid disorders.

Choice B rationale:

Asthma is not a contraindication for niacin use. Niacin does not interact with asthma medications or worsen asthma symptoms, so it is not contraindicated in individuals with asthma.

Choice C rationale:

High blood pressure is not a contraindication for niacin use. In fact, niacin can help lower blood pressure and improve overall cardiovascular health. It is often prescribed to individuals with high blood pressure and elevated cholesterol levels.

Choice D rationale:

Active liver disease is a contraindication for niacin use. Niacin can cause liver damage, and individuals with active liver disease should avoid niacin therapy to prevent further harm to the liver. Monitoring liver function tests is crucial in patients taking niacin to ensure their liver health.

Correct Answer is A

Explanation

Choice A rationale:

A blood lead level of 18 mcg/dL in a 9-month-old infant is elevated. The Centers for Disease Control and Prevention (CDC) considers a blood lead level of 5 mcg/dL or higher in children to be concerning. Lead exposure can lead to developmental delays and cognitive impairments. Therefore, this result needs to be reported to the healthcare provider promptly.

Choice B rationale:

Hemoglobin level of 12 g/dL is within the normal range for a 9-month-old infant (11-15 g/dL) There is no need to report this result to the provider.

Choice C rationale:

Iron level of 74 mcg/dL is within the normal range for a 9-month-old infant (50-120 mcg/dL) There is no need to report this result to the provider.

Choice D rationale:

Hematocrit level of 35% is within the normal range for a 9-month-old infant (29-41%) There is no need to report this result to the provider.

A. Hemoglobin 14.9 g/dL B. WBC count 12.000/mm C. Potassium 48 mEq D. BUN 18 mg/dL

Correct Answer is A

Explanation

A. Correct. A hemoglobin level of 14.9 g/dL indicates that the client has an adequate amount of oxygen-carrying capacity in the blood, which is the goal of blood transfusion therapy.
B. Incorrect. A WBC count of 12,000/mm3 is slightly elevated and may indicate an infection or inflammation, which are not related to blood transfusion therapy.
C. Incorrect. A potassium level of 48 mEq/L is dangerously high and may cause cardiac arrhythmias, muscle weakness, or paralysis. This is not an expected outcome of blood transfusion therapy and may indicate hemolysis or renal impairment.
D. Incorrect. A BUN level of 18 mg/dL is within the normal range and does not reflect the effectiveness of blood transfusion therapy.
