Nursing Elites

1. A client presenting with complaints of not feeling well is seen in a clinic. The client is taking several medications for the control of heart disease and hypertension, including a beta-blocker, digoxin (Lanoxin), and a diuretic. A tentative diagnosis of digoxin toxicity is made. Which of the following assessment data would support this diagnosis?

• A. Dyspnea, edema, and palpitations
• B. Chest pain, hypotension, and paresthesia
• C. Double vision, loss of appetite, and nausea
• D. Constipation, dry mouth, and sleep disorder

Correct answer: C

Rationale: The correct answer is C. Double vision, loss of appetite, and nausea are classic signs of digoxin toxicity. Other signs may include bradycardia, visual disturbances, and confusion. These symptoms are indicators that the client may be experiencing adverse effects due to elevated levels of digoxin in the system, requiring immediate medical attention to prevent serious complications.

2. Heparin sodium is prescribed for the client. The nurse expects that the healthcare provider will prescribe which of the following to monitor for a therapeutic effect of the medication?

• A. Hematocrit level
• B. Hemoglobin level
• C. Prothrombin time (PT)
• D. Activated partial thromboplastin time (aPTT)

Correct answer: D

Rationale: The correct answer is D, activated partial thromboplastin time (aPTT). Heparin affects the intrinsic pathway of coagulation. Monitoring aPTT helps ensure that heparin sodium is within the therapeutic range to prevent clot formation. Hematocrit and hemoglobin levels assess red blood cell concentrations and are not specific to monitoring heparin therapy. Prothrombin time (PT) is used to monitor the therapeutic effect of warfarin sodium, which affects the extrinsic pathway of coagulation, not heparin.

3. A client taking fexofenadine (Allegra) is scheduled for allergy skin testing and tells the nurse in the healthcare provider's office that a dose was taken this morning. The nurse determines that:

• A. The client should reschedule the appointment.
• B. A lower dose of allergen will need to be injected.
• C. A higher dose of allergen will need to be injected.
• D. The client should have the skin test read a day later than usual.

Correct answer: A

Rationale: Fexofenadine, an antihistamine, can cause false-negative readings in allergy skin testing and should be discontinued 3 days prior. Therefore, the client should reschedule the appointment to ensure accurate test results.

4. Tamoxifen is prescribed for the client with metastatic breast carcinoma. The nurse understands that the primary action of this medication is to:

• A. Increase DNA and RNA synthesis.
• B. Promote the biosynthesis of nucleic acids.
• C. Increase estrogen concentration and estrogen response.
• D. Compete with estradiol for binding to estrogen in tissues containing high concentrations of receptors.

Correct answer: D

Rationale: The primary action of tamoxifen, an antineoplastic medication used in metastatic breast carcinoma, is to compete with estradiol for binding to estrogen receptors in tissues with high receptor concentrations. By doing so, tamoxifen reduces DNA synthesis and estrogen response, leading to its therapeutic effect in inhibiting the growth of estrogen-sensitive breast cancer cells.

5. A clinic nurse prepares to administer an MMR (measles, mumps, rubella) vaccine to a child. How is this vaccine best administered?

• A. Intramuscularly in the deltoid muscle
• B. Subcutaneously in the gluteal muscle
• C. Subcutaneously in the outer aspect of the upper arm
• D. Intramuscularly in the anterolateral aspect of the thigh

Correct answer: C

Rationale: The MMR vaccine is best administered subcutaneously in the outer aspect of the upper arm. This route allows for proper absorption and efficacy of the vaccine while minimizing the risk of injury or discomfort to the child.
