Nursing Elites

1. A 70-year-old woman presents with fatigue, anorexia, and weight loss. She has noticed darkening of her skin, particularly in sun-exposed areas. Laboratory tests reveal hyponatremia, hyperkalemia, and low cortisol levels. What is the most likely diagnosis?

• A. Cushing's syndrome
• B. Addison's disease
• C. Hypothyroidism
• D. Pheochromocytoma

Correct answer: B

Rationale: The combination of symptoms such as fatigue, anorexia, weight loss, hyperpigmentation of the skin, along with hyponatremia, hyperkalemia, and low cortisol levels, points towards Addison's disease. This condition is characterized by adrenal insufficiency, leading to a deficiency in cortisol and aldosterone production.

2. An elderly male client reports to the clinic nurse that he is experiencing increasing nocturia with difficulty initiating his urine stream. He reports a weak urine flow and frequent dribbling after voiding. Which nursing action should be implemented?

• A. Obtain a urine specimen for culture and sensitivity.
• B. Encourage the client to schedule a digital rectal exam.
• C. Advise the client to maintain a voiding diary for one week.
• D. Instruct the client in effective techniques for cleansing the glans penis.

Correct answer: B

Rationale: Encouraging the client to schedule a digital rectal exam is the most appropriate nursing action in this situation. This exam can help evaluate for potential prostate enlargement or other issues contributing to the urinary symptoms described by the client. It is important to assess the prostate gland for any abnormalities that may be causing the urinary issues reported by the client.

3. A healthcare professional is educating a group of recent nursing graduates about their risks for contracting hepatitis B. What preventative measure should the professional promote?

• A. Immunization
• B. Chronic tonsillitis
• C. Consumption of a vitamin-rich diet
• D. Annual vitamin K injections

Correct answer: A

Rationale: The correct preventative measure to promote for preventing hepatitis B infection is immunization. Healthcare workers, including nurses, are at risk of exposure to hepatitis B, and vaccination is crucial in preventing infection. Immunization, along with adherence to standard precautions such as using personal protective equipment, proper hand hygiene, and safe needle practices, plays a vital role in protecting healthcare workers from contracting hepatitis B.

4. A patient with hyperthyroidism is prescribed propylthiouracil (PTU). What is the primary purpose of this medication?

• A. Increase thyroid hormone production
• B. Suppress thyroid hormone production
• C. Enhance iodine absorption
• D. Stimulate the thyroid gland

Correct answer: B

Rationale: Propylthiouracil (PTU) is a medication used to treat hyperthyroidism by suppressing the production of thyroid hormones. It works by inhibiting the enzyme responsible for the synthesis of thyroid hormones, thereby reducing their levels in the body. This helps to alleviate the symptoms of hyperthyroidism and restore thyroid hormone levels to normal range.

5. A client with deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to assess the effectiveness of the therapy?

• A. Prothrombin time (PT)
• B. Platelet count
• C. Activated partial thromboplastin time (aPTT)
• D. International normalized ratio (INR)

Correct answer: C

Rationale: Activated partial thromboplastin time (aPTT) is the appropriate laboratory test to monitor the effectiveness of heparin therapy. Heparin works by prolonging the clotting time, which is reflected in the aPTT results. Monitoring aPTT helps ensure the patient is within the therapeutic range and not at risk of bleeding or clotting complications. Prothrombin time (PT) (Choice A) primarily measures the extrinsic pathway of coagulation and is used to monitor warfarin therapy, not heparin. Platelet count (Choice B) assesses the number of platelets present in the blood and is not specific to monitoring heparin therapy. International normalized ratio (INR) (Choice D) is used to monitor warfarin therapy, not heparin.
