A nurse is reviewing the medical record of a client who has schizophrenia and is taking clozapine.
Which of the following findings should the nurse identify as a contraindication to the administration of clozapine?

Heart rate 58/min.

Fasting blood glucose 100 mg/dL.

WBC count 2,900/mm3.

Hgb 14 g/dL.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Heart rate 58/min. Clozapine, an atypical antipsychotic medication, can cause bradycardia (slow heart rate) as a side effect. However, the heart rate of 58/min is within the normal range for adults, so it is not a contraindication for clozapine administration.

Choice B rationale:

Fasting blood glucose 100 mg/dL. A fasting blood glucose level of 100 mg/dL is within the normal range (70-99 mg/dL) for adults. It is not a contraindication for clozapine administration.

Choice C rationale:

WBC count 2,900/mm3. Clozapine can cause agranulocytosis, a severe reduction in white blood cell (WBC) count, which can lead to increased susceptibility to infections. A WBC count of 2,900/mm3 is significantly below the normal range (4,000-11,000/mm3) and is a contraindication for clozapine administration due to the risk of severe immunosuppression.

Choice D rationale:

Hgb 14 g/dL. Hemoglobin (Hgb) level of 14 g/dL is within the normal range for adult males (13.8-17.2 g/dL) and females (12.1-15.1 g/dL). It is not a contraindication for clozapine administration.

Correct Answer is A

Explanation

Choice A rationale:

Lavender oil is commonly used in aromatherapy and is known for its calming effects. However, it can trigger respiratory issues in individuals with asthma. Asthma is a chronic condition characterized by airway inflammation and bronchoconstriction, which can be exacerbated by inhaling certain substances, including strong odors and essential oils. Lavender oil, when inhaled, can potentially irritate the airways and worsen asthma symptoms. Therefore, a history of asthma is a contraindication for using lavender oil.

Choice B rationale:

Furosemide is a diuretic commonly used to treat fluid retention (edema) and hypertension. It works by increasing urine production and removing excess fluid from the body. Furosemide does not interact with lavender oil directly, and there is no known contraindication between these two substances.

Choice C rationale:

Alcohol use disorder is a condition characterized by an inability to control or stop alcohol consumption despite negative consequences. While alcohol abuse can have various health implications, it does not specifically interact with lavender oil in a way that constitutes a contraindication.

Choice D rationale:

Vitamin C is a water-soluble vitamin that plays a crucial role in various bodily functions, including immune system support and collagen synthesis. There is no evidence to suggest that taking vitamin C daily contraindicates the use of lavender oil. These two substances do not interact in a way that poses a risk to the individual.

A. Maintain bed elevation at 20 degrees. B. Flush the tubing with 30 mL of water every 4 hr. C. Check for gastric residual every 12 hr. D. Place enough formula in the container to last 18 hr.

Correct Answer is B

Explanation

The correct answer is Choice B.

Choice A rationale: Maintaining bed elevation at 20 degrees is not recommended. The recommended bed elevation for patients receiving enteral tube feedings is at least 30 to 45 degrees.This is to prevent aspiration of the feeding solution into the lungs.

Choice B rationale: Flushing the tubing with 30 mL of water every 4 hours is a recommended practice.This helps to maintain the patency of the feeding tube and prevent clogging.

Choice C rationale: Checking for gastric residual every 12 hours is not sufficient.For patients receiving continuous tube feedings, gastric residual volume (GRV) should be monitored every 4 hours.This helps to assess tolerance to the feeding and prevent complications such as aspiration.

Choice D rationale: Placing enough formula in the container to last 18 hours is not recommended.For an open system, the formula should be replaced every 4 hours to prevent bacterial growth.
