A client is prescribed ondansetron for nausea. When reviewing the client's medical history, which finding would concern the nurse?

Cerebral Vascular Accident

Depression

Glaucoma

Congestive Heart Failure

Answer and Explanation

The Correct Answer is C

A) Cerebral Vascular Accident (CVA): While a history of a CVA (stroke) is important to consider when prescribing medications, ondansetron is not contraindicated for clients with a history of CVA. The nurse would need to assess the client’s overall neurological status and risk factors but this condition is not an immediate concern for ondansetron use.

B) Depression: Ondansetron is not typically contraindicated in patients with depression. However, the nurse should be mindful of the potential for interactions with other medications the client may be taking for depression, but there is no direct contraindication between ondansetron and depression itself.

C) Glaucoma: This is the most concerning finding. Ondansetron can increase the risk of complications in clients with glaucoma, particularly narrow-angle glaucoma. Ondansetron has some serotonin receptor-blocking properties that can cause dilation of the pupil, which could increase intraocular pressure in clients with glaucoma. Therefore, this condition would require careful monitoring, and the nurse would need to consult with the healthcare provider before administering ondansetron to a client with glaucoma.

D) Congestive Heart Failure (CHF): While patients with CHF need to be monitored for fluid balance, ondansetron is not contraindicated in clients with CHF. The primary concern in these patients would be potential fluid retention or electrolyte imbalances, but this is generally not a direct concern for the administration of ondansetron itself.

Correct Answer is ["4"]

Explanation

Convert micrograms (mcg) to milligrams (mg):

The prescribed dose is 200 mcg.

We know that 1 mg = 1000 mcg.

Therefore, 200 mcg = 200 / 1000 = 0.2 mg.

Calculate the number of tablets:

Each tablet contains 0.05 mg of levothyroxine.

The desired dose is 0.2 mg.

We can use the following formula: (Desired dose) / (Tablet strength) = Number of tablets

(0.2 mg) / (0.05 mg/tablet) = 4 tablets

A. Peptic ulcer B. Asthma C. Heart disease D. Glaucoma

Correct Answer is D

Explanation

A) Peptic ulcer: Scopolamine is an anticholinergic medication that works by blocking acetylcholine, which can reduce nausea and motion sickness. While scopolamine can have anticholinergic effects that may slightly reduce gastric motility, it is not directly contraindicated in clients with a history of peptic ulcer. The medication does not significantly exacerbate the condition of peptic ulcers.

B) Asthma: While scopolamine can have anticholinergic effects that may lead to dry mouth and slight airway narrowing, it is not contraindicated in clients with asthma. However, the nurse should be cautious and monitor the client for any signs of respiratory distress, as anticholinergic medications can cause some bronchial smooth muscle relaxation, which could theoretically worsen asthma symptoms. It is not an absolute contraindication.

C) Heart disease: Scopolamine is not specifically contraindicated for individuals with heart disease, although caution should be used in patients with cardiovascular conditions due to its potential effects on heart rate and blood pressure. However, heart disease itself is not a direct contraindication for the use of scopolamine.

D) Glaucoma: Scopolamine is an anticholinergic medication, and anticholinergics can increase intraocular pressure. This is especially dangerous for clients with narrow-angle glaucoma, as the medication can exacerbate the condition, leading to a potential acute glaucoma attack. Therefore, individuals with a history of glaucoma, particularly narrow-angle glaucoma, should avoid scopolamine.
