A 48-year-old man presents with fatigue, weight gain, and cold intolerance. 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 scenario describes a classic presentation of hypothyroidism, supported by the laboratory findings of high TSH and low free T4 levels. In hypothyroidism, the body's thyroid hormone levels are inadequate, leading to symptoms like fatigue, weight gain, and cold intolerance. High TSH is a compensatory mechanism by the body to increase thyroid hormone production, which is deficient, resulting in a negative feedback loop. Therefore, the correct answer is hypothyroidism.

The charge nurse observes that a client with a nasogastric tube on low intermittent suction is drinking a glass of water immediately after the unlicensed assistive personnel (UAP) left the room. What action should the nurse take?

• A. Remove the glass of water and speak to the UAP.
• B. Discuss the incident with the UAP at the end of the day.
• C. Write an incident report and notify the healthcare provider.
• D. Remind the client of the potential for electrolyte imbalance.

Correct Answer: A
Rationale: The correct action for the charge nurse to take is to remove the glass of water and speak to the UAP. This ensures immediate correction and education to prevent further issues with the nasogastric tube. Addressing the situation promptly can prevent harm to the client and reinforces the importance of following proper protocols.

The nurse is planning care for a 16-year-old with juvenile rheumatoid arthritis (JRA). The nurse includes activities to strengthen and mobilize the joints and surrounding muscles. Which physical therapy regimen should the nurse encourage the adolescent to implement?

• A. Exercise in a swimming pool.
• B. Splint affected joints during activity.
• C. Perform passive range of motion exercises twice daily.
• D. Begin a training program of lifting weights and running.

Correct Answer: A
Rationale: Exercising in a swimming pool is beneficial for adolescents with juvenile rheumatoid arthritis as it reduces stress on the joints while allowing movement and strengthening. The buoyancy of water supports the body, making exercises easier and less painful, while also providing resistance to strengthen muscles. This form of exercise can help improve joint mobility and overall function without causing excessive strain on the joints. Choices B, C, and D are incorrect because splinting affected joints, performing passive range of motion exercises, or beginning a training program of lifting weights and running can potentially exacerbate symptoms and cause additional stress on the joints, which is not recommended for individuals with juvenile rheumatoid arthritis.

A client with hypertension is receiving dietary education from a nurse. Which recommendation should the nurse include?

• A. Increase your intake of saturated fats.
• B. Limit your sodium intake to less than 2 grams per day.
• C. Avoid foods high in potassium.
• D. Consume at least three alcoholic beverages daily.

Correct Answer: B
Rationale: The correct recommendation for a client with hypertension is to limit sodium intake to less than 2 grams per day. High sodium intake can worsen hypertension by increasing blood pressure. Choices A, C, and D are incorrect. Increasing saturated fats (Choice A) can be detrimental to heart health and exacerbate hypertension. Avoiding foods high in potassium (Choice C) is not recommended as potassium-rich foods can actually be beneficial for managing blood pressure. Consuming three alcoholic beverages daily (Choice D) can also have a negative impact on blood pressure and overall health.

A 40-year-old woman presents with a history of chronic constipation, bloating, and abdominal pain. She notes that the pain is relieved with defecation. She denies any weight loss, blood in her stools, or nocturnal symptoms. Physical examination and routine blood tests are normal. What is the most likely diagnosis?

• A. Inflammatory bowel disease
• B. Irritable bowel syndrome
• C. Celiac disease
• D. Lactose intolerance

Correct Answer: B
Rationale: The patient's symptoms of chronic constipation, bloating, abdominal pain relieved with defecation, absence of weight loss, blood in stools, or nocturnal symptoms, along with normal physical examination and routine blood tests, are indicative of irritable bowel syndrome (IBS). IBS is a functional gastrointestinal disorder characterized by abdominal pain or discomfort and altered bowel habits in the absence of any organic cause. It is a diagnosis of exclusion made based on symptom criteria, and the provided clinical scenario aligns with the typical presentation of IBS.
