Nursing Elites

1. A 60-year-old man 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 presentation of a 60-year-old man with fatigue, polyuria, polydipsia, hyperglycemia, and ketonuria strongly suggests type 1 diabetes mellitus. Type 1 diabetes typically presents with acute symptoms due to absolute insulin deficiency, leading to hyperglycemia and ketonuria. Conversely, type 2 diabetes often presents more insidiously and is associated with relative insulin deficiency and insulin resistance. Diabetes insipidus, a condition characterized by excessive thirst and excretion of large amounts of dilute urine, is due to problems with antidiuretic hormone (ADH) and is not associated with hyperglycemia or ketonuria. Hyperthyroidism, while also presenting with symptoms like fatigue, does not typically manifest with hyperglycemia or ketonuria. Therefore, based on the clinical presentation and laboratory findings, the most likely diagnosis in this case is type 1 diabetes mellitus.

2. A client with a history of hypertension is prescribed hydrochlorothiazide. Which instruction should the nurse include in the client's teaching?

• A. Take this medication in the morning.
• B. Avoid foods high in potassium.
• C. Monitor your blood pressure regularly.
• D. Decrease your intake of high-sodium foods.

Correct answer: C

Rationale: Regular monitoring of blood pressure is crucial for individuals with hypertension to assess the effectiveness of the prescribed medication and to ensure blood pressure is within the target range. This helps in managing hypertension and preventing complications associated with high blood pressure. Choices A, B, and D are incorrect because while taking the medication in the morning may be recommended for some drugs, it is not the key instruction for hydrochlorothiazide. Avoiding foods high in potassium and decreasing high-sodium foods are important dietary considerations for certain conditions, but they are not the immediate focus when starting hydrochlorothiazide.

3. What is/are the possible cause(s) of acute pancreatitis in this patient?

• A. HIV
• B. Cytomegalovirus
• C. Dideoxyinosine (ddI)
• D. Pentamidine

Correct answer: B

Rationale: This patient presents with symptoms and lab findings consistent with acute pancreatitis. Cytomegalovirus is a common viral infection associated with pancreatitis. In patients with AIDS, the pancreas can be affected by various infections (e.g., cryptococcus, Mycobacterium tuberculosis, candida, Toxoplasma gondii) and medications (such as ddI, pentamidine, trimethoprim/sulfamethoxazole, metronidazole) can also lead to acute pancreatitis. While HIV infection predisposes individuals to various opportunistic infections, in this case, the most likely cause of the acute pancreatitis is cytomegalovirus infection.

4. 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.

5. A 35-year-old man presents with difficulty swallowing, weight loss, and regurgitation of undigested food. A barium swallow shows a 'bird beak' appearance of the lower esophagus. What is the most likely diagnosis?

• A. Esophageal cancer
• B. Achalasia
• C. Peptic stricture
• D. Gastroesophageal reflux disease

Correct answer: B

Rationale: The 'bird beak' appearance on a barium swallow is characteristic of achalasia, a condition where the lower esophageal sphincter fails to relax properly. This leads to difficulty swallowing, weight loss, and regurgitation of undigested food, which are hallmark symptoms of achalasia.
