A nurse is preparing to administer levothyroxine 50 mcg to a client. Available is levothyroxine 0.025 mg/tablet. How many tablets should the nurse administer per dose? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation

The Correct Answer is ["2"]

Rationale:

  • Convert the ordered dose to milligrams

Conversion factor: 1 mg = 1000 mcg

Ordered Dose: 50 mcg = 0.05 mg

  • Identify the available tablet strength

Available Tablet Strength: 0.025 mg/tablet

  • Calculate the number of tablets per dose

Number of Tablets = Dose ÷ Tablet Strength

        = 0.05 ÷ 0.025

        = 2 tablets

Correct Answer is A

Explanation

A. Screen the child's visitors for active infections: Children with neutropenia have a significantly reduced ability to fight infections due to low neutrophil counts. Screening visitors for signs of infection helps prevent exposure to pathogens, which is a critical infection-control measure in neutropenic patients.

B. Monitor the child for indications of active bleeding: While monitoring for bleeding is important in leukemia, bleeding risk is primarily related to thrombocytopenia, not neutropenia. This intervention is relevant but not the priority for infection prevention.

C. Initiate a low-protein diet for the child: A low-protein diet is not indicated and may be harmful, as children with leukemia require adequate protein for growth, immune function, and recovery. Dietary restrictions should focus on food safety, not protein limitation.

D. Prepare the child for a platelet transfusion: Platelet transfusions are indicated for thrombocytopenia, not neutropenia. While supportive care may include transfusions, infection prevention through visitor screening is more directly related to neutropenic risk.

Correct Answer is A

Explanation

A. "This type of seizure can be mistaken for daydreaming.": Absence seizures are brief, sudden episodes of impaired consciousness, often with staring and subtle motor activity. Because these episodes are very short and the child resumes normal activity immediately, they can easily be misinterpreted as inattentiveness or daydreaming.

B. "This type of seizure lasts 30 to 60 seconds.": Absence seizures are typically very brief, usually lasting 5 to 10 seconds, rarely up to 15 seconds. A duration of 30 to 60 seconds is longer than expected and more characteristic of other seizure types.

C. "The child usually has an aura prior to onset.": Absence seizures do not usually have a preceding aura. Auras are more commonly associated with focal or partial seizures, not generalized absence seizures.

D. "This type of seizure has a gradual onset.": Absence seizures have a sudden onset and end abruptly. There is no gradual buildup of symptoms, which helps differentiate them from other neurological or behavioral events.
