Nursing Elites

1. A healthcare professional is preparing to administer digoxin 0.25 mg PO daily. The amount available is digoxin 0.125 mg tablets. How many tablets should the healthcare professional administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

• A. 1
• B. 2
• C. 3
• D. 4

Correct answer: B

Rationale: To achieve the prescribed dose of 0.25 mg, the healthcare professional should administer 2 tablets of 0.125 mg each, totaling 0.25 mg.

2. A client with a history of diabetes mellitus is admitted with a foot ulcer. The nurse should recognize that which intervention is most critical in promoting healing of the foot ulcer?

• A. Strict control of blood glucose levels.
• B. Regular dressing changes with sterile technique.
• C. Application of antibiotic ointment.
• D. Hydrotherapy treatment daily.

Correct answer: A

Rationale: In diabetic clients with foot ulcers, strict control of blood glucose levels is essential for promoting wound healing. High blood glucose levels can impair circulation and compromise the body's ability to fight infection, delaying the healing process. By maintaining optimal blood glucose levels, the client's overall health and wound healing potential are improved.

3. A client is being treated with an antidepressant for major depressive disorder. Which statement by the client indicates a need for further teaching?

• A. I know it may take several weeks before I start feeling better.
• B. I should avoid drinking alcohol while taking this medication.
• C. I will stop taking the medication as soon as I feel better.
• D. I should take the medication at the same time every day.

Correct answer: C

Rationale: Choice C indicates a need for further teaching because stopping antidepressants abruptly can lead to withdrawal symptoms. It is essential for the client to follow the healthcare provider's instructions and complete the full course of medication even if they start feeling better to prevent potential relapse or withdrawal effects.

4. A 45-year-old woman presents with fatigue, weight gain, and constipation. Laboratory tests reveal high TSH and low free T4 levels. What is the most likely diagnosis?

• A. Hypothyroidism
• B. Hyperthyroidism
• C. Thyroiditis
• D. Thyroid cancer

Correct answer: A

Rationale: The combination of high TSH and low free T4 levels is consistent with hypothyroidism, which matches the patient's symptoms of fatigue, weight gain, and constipation. In hypothyroidism, the thyroid gland does not produce enough thyroid hormones, leading to a decrease in metabolic rate and resulting in these clinical findings.

5. A 40-year-old woman presents with fatigue, polyuria, and polydipsia. Laboratory tests reveal hyperglycemia and ketonuria. What is the most likely diagnosis?

• A. Type 1 diabetes mellitus
• B. Type 2 diabetes mellitus
• C. Diabetes insipidus
• D. Hyperthyroidism

Correct answer: A

Rationale: The combination of symptoms including fatigue, polyuria, polydipsia, along with laboratory findings of hyperglycemia and ketonuria strongly suggest type 1 diabetes mellitus. In type 1 diabetes mellitus, there is a deficiency of insulin leading to high blood sugar levels (hyperglycemia) and the breakdown of fats producing ketones, causing ketonuria. Type 2 diabetes mellitus typically presents differently and is more common in older individuals. Diabetes insipidus is characterized by excessive thirst and urination due to a deficiency of antidiuretic hormone, distinct from the provided clinical scenario. Hyperthyroidism may present with some overlapping symptoms like fatigue, but it does not account for the specific laboratory findings of hyperglycemia and ketonuria seen in this case.
