The nurse should monitor the client for signs and symptoms of digoxin toxicity if the laboratory report reflects a serum:

sodium of 133 mg/dl.

glucose of 110 mg/dl.

potassium of 3.0 mEq/L.

calcium of 9.0 mg/dl.

Answer and Explanation

The Correct Answer is C

C. Digoxin toxicity is a serious condition that can occur when there is too much digoxin in the body. It can lead to life-threatening cardiac dysrhythmias. One of the risk factors for digoxin toxicity is low blood levels of potassium, or hypokalemia.
A. Electrolyte imbalances, including hyponatremia (low sodium levels), can contribute to digoxin toxicity. However, a sodium level of 133 mg/dl alone does not directly indicate digoxin toxicity.
B. Blood glucose levels within the normal range (80-120 mg/dl) would not directly indicate digoxin toxicity.
D. Calcium levels within the normal range (8.5-10.5 mg/dl) do not directly indicate digoxin toxicity.

Correct Answer is B

Explanation

B. In the United States, the legal limit for blood alcohol concentration (BAC) is 0.08%. A BAC of 0.11 g/dL exceeds this limit, indicating that the client is indeed legally intoxicated.
A. Psychomotor tests, such as field sobriety tests, may be performed to assess the client's level of impairment and determine if they are intoxicated when the BAL is below threshold for intoxication.
C. State laws do not vary in this regard for the legal limit of BAC for driving; however, penalties and specific charges can vary from state to state.
D. A blood alcohol level (BAL) of 0.11 g/dL is above the legal limit for driving in many jurisdictions, where the legal limit is typically set at 0.08 g/dL.

A. "They may cause hypomania or recent memory impairment." B. "Their full therapeutic potential may not be reached until 4 weeks." C. "They should not be given with antianxiety agents." D. "Strong or aged cheese should not be eaten while taking them."

Correct Answer is B

Explanation

B. Tricyclic antidepressants (TCAs) are known to take some time before their full therapeutic effects are realized, which can indeed be up to four weeks. This delay is due to the gradual changes they induce in the brain's biochemistry.
A. TCAs can cause a variety of side effects but hypomania and recent memory impairment are not typically associated with these medications.
C. TCAs do not have a known interaction with antianxiety agents that would prohibit their concurrent use.
D. The restriction on eating strong or aged cheese is associated with another class of antidepressants known as monoamine oxidase inhibitors (MAOIs), not TCAs.
