1. A 30-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 clinical presentation of a 30-year-old woman with fatigue, polyuria, polydipsia, hyperglycemia, and ketonuria is highly suggestive of type 1 diabetes mellitus. Type 1 diabetes mellitus is characterized by autoimmune destruction of pancreatic beta cells, leading to insulin deficiency and subsequent hyperglycemia. The presence of ketonuria indicates the breakdown of fats for energy due to the lack of insulin. In contrast, type 2 diabetes mellitus typically presents with gradual onset and is often associated with insulin resistance rather than absolute insulin deficiency. Diabetes insipidus is characterized by polyuria and polydipsia but is not associated with hyperglycemia or ketonuria. Hyperthyroidism may present with symptoms like fatigue but does not typically cause hyperglycemia or ketonuria.
2. In a 45-year-old woman with a history of arthritis experiencing severe heartburn and indigestion refractory to antacids, which findings on an esophageal manometry study are consistent with her diagnosis?
- A. Vigorous peristalsis and elevated lower esophageal sphincter (LES) pressure
- B. Absent peristalsis and elevated LES pressure
- C. Absent peristalsis and decreased LES pressure
- D. Vigorous peristalsis and decreased LES pressure
Correct answer: C
Rationale: The correct answer is C: Absent peristalsis and decreased lower esophageal sphincter (LES) pressure. The patient in this scenario has scleroderma esophagus, characterized by atrophy of esophageal smooth muscle, leading to the loss of peristalsis and LES tone. These changes contribute to severe symptoms of gastroesophageal reflux disease (GERD) and esophagitis. Absent peristalsis and decreased LES pressure are typical findings in scleroderma esophagus, contributing to the refractory nature of the patient's symptoms despite antacid use.
3. A patient with diabetes insipidus is prescribed desmopressin. What is the primary purpose of this medication?
- A. Increase urine output
- B. Reduce blood sugar levels
- C. Decrease urine output
- D. Lower blood pressure
Correct answer: C
Rationale: Desmopressin is prescribed to decrease urine output in patients with diabetes insipidus. It works by increasing water reabsorption in the kidneys, helping to control fluid balance in the body.
4. A 65-year-old female client arrives in the emergency department with shortness of breath and chest pain. The nurse accidentally administers 10 mg of morphine sulfate instead of the prescribed 4 mg. Later, the client's respiratory rate is 10 breaths/minute, oxygen saturation is 98%, and she states her pain has subsided. What is the legal status of the nurse?
- A. The nurse is guilty of negligence and will be sued.
- B. The client would not be able to prove malpractice in court.
- C. The nurse is protected by the Good Samaritan Act.
- D. The healthcare provider should have given the morphine sulfate dose.
Correct answer: B
Rationale: The correct answer is B because, in this scenario, the client would not be able to prove malpractice in court. Despite the nurse administering a higher dose of morphine than prescribed, the client's respiratory rate, oxygen saturation, and pain relief indicate that no harm resulted from the error. Therefore, the client would not have legal grounds to pursue a malpractice case against the nurse.
5. A client with acute pancreatitis is admitted to the hospital. What is the priority nursing intervention for this client?
- A. Administering oral pancreatic enzymes
- B. Encouraging a high-protein diet
- C. Maintaining NPO status and administering IV fluids
- D. Providing a low-fat diet
Correct answer: C
Rationale: The priority nursing intervention for a client with acute pancreatitis is to maintain NPO (nothing by mouth) status and administer IV fluids. This approach helps rest the pancreas, decrease pancreatic stimulation, and prevent further exacerbation of the condition. By withholding oral intake and providing IV fluids, the pancreas is given the opportunity to recover and inflammation can be reduced. This intervention is crucial in the acute phase of pancreatitis to support the healing process and prevent complications.
