1. After multiple attempts to stop drinking, an adult male is admitted to the medical intensive care unit (MICU) with delirium tremens. He is tachycardic, diaphoretic, restless, and disoriented. Which finding indicates a life-threatening condition?
- A. Widening QRS complexes and flat T waves
- B. Tachycardia and elevated blood pressure
- C. Restlessness and anxiety
- D. Diaphoresis and dehydration
Correct answer: A
Rationale: The correct answer is A: Widening QRS complexes and flat T waves. In the context of an adult male with delirium tremens and symptoms like tachycardia, diaphoresis, restlessness, and disorientation, the presence of widening QRS complexes and flat T waves on an ECG suggests severe electrolyte imbalance, particularly hypokalemia. This severe electrolyte imbalance can lead to life-threatening arrhythmias such as ventricular tachycardia or fibrillation. Tachycardia and elevated blood pressure (choice B) can be expected in delirium tremens but do not directly indicate a life-threatening condition as widening QRS complexes and flat T waves do. Restlessness and anxiety (choice C) are common symptoms of delirium tremens but do not specifically signify a life-threatening condition. Diaphoresis and dehydration (choice D) are also common in delirium tremens but do not directly point towards a life-threatening electrolyte imbalance as widening QRS complexes and flat T waves do.
2. A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which laboratory value requires immediate intervention?
- A. Serum glucose of 600 mg/dL
- B. Serum osmolarity of 320 mOsm/kg
- C. Serum sodium of 130 mEq/L
- D. Serum potassium of 5.0 mEq/L
Correct answer: B
Rationale: A serum osmolarity of 320 mOsm/kg is concerning in a client with HHS because it indicates severe dehydration and hyperosmolarity, which requires immediate intervention. In HHS, the elevated serum osmolarity leads to neurological symptoms and can result in serious complications if not addressed promptly. While a high serum glucose level (choice A) is typical in HHS, the osmolarity is a more direct indicator of dehydration and severity. Serum sodium (choice C) and potassium levels (choice D) are important but do not pose an immediate threat to the client's condition compared to the severe hyperosmolarity indicated by a high serum osmolarity level.
3. While auscultating a client's heart sounds, which description should the nurse use to document a swishing sound related to blood turbulence or valvular defect?
- A. S1 S2
- B. S1 S2 S3
- C. Murmur
- D. Pericardial friction rub
Correct answer: C
Rationale: The correct answer is 'C: Murmur.' A murmur is auscultated as a swishing sound associated with blood turbulence caused by the heart or a valvular defect. Choices 'A: S1 S2' and 'B: S1 S2 S3' refer to normal heart sounds, specifically the closure of heart valves. 'D: Pericardial friction rub' is a dry, rubbing or grating sound caused by inflammation of the pericardial sac and is not associated with blood flow or valvular issues.
4. A 3-year-old boy with a congenital heart defect is brought to the clinic by his mother. During the assessment, the mother asks the nurse why her child is at the 5th percentile for growth. What response is best for the nurse to provide?
- A. Does your child seem mentally slower than his peers also?
- B. His smaller size is probably due to the heart disease
- C. Haven't you been feeding him according to recommended daily allowances for children?
- D. You should not worry about the growth tables. They are only averages for children
Correct answer: B
Rationale: Heart disease can affect growth, leading to smaller size in children.
5. A male client is prescribed clozapine (Clozaril), an antipsychotic medication, for the management of schizophrenia. Which client history should the nurse report to the healthcare provider before administering the first dose of this medication?
- A. History of depression
- B. History of cardiac arrhythmia
- C. History of seizures
- D. History of diabetes mellitus
Correct answer: B
Rationale: The correct answer is B: History of cardiac arrhythmia. Clozapine can lead to severe cardiovascular problems, making it crucial to report any history of cardiac arrhythmia to the healthcare provider before administering the medication. Choices A, C, and D are less concerning in this context as they are not directly associated with potential serious complications related to clozapine use.
