Question 1 of 5
Which of the following findings would necessitate discontinuing an IV potassium infusion in an adult with ketoacidosis?
Correct Answer: A
Rationale: Adequate renal flow of 30 mL/hr is a necessity with potassium infusions because potassium is excreted renally. Because potassium level will decrease during correction of diabetic ketoacidosis, potassium will be infused even if plasma levels of potassium are normal. A small T wave is normal and desired on the electrocardiogram. A tall, peaked T-wave could indicate overinfusion of potassium and hyperkalemia. Glucose levels of <200 are desirable.
Question 2 of 5
A 44-year-old client had an emergency cholecystectomy 3 days ago for a ruptured gallbladder. She complains of severe abdominal pain. Assessment reveals abdominal rigidity and distention, increased temperature, and tachycardia. Diagnostic testing reveals an elevated WBC count. The nurse suspects that the client has developed:
Correct Answer: C
Rationale: Assessment findings for gastritis would reveal anorexia, nausea and vomiting, epigastric fullness and tenderness, and discomfort. Evisceration is the extrusion of abdominal viscera as a result of trauma or sutures failing in a surgical incision. Peritonitis, inflammation of the peritoneum, can occur when an abdominal organ, such as the gallbladder, perforates and leaks blood and fluid into the abdominal cavity. This causes infection and irritation. Assessment findings of pulmonary embolism would reveal severe substernal chest pain, tachycardia, tachypnea, shortness of breath, anxiety or panic, and wheezing and coughing often accompanied by blood-tinged sputum.
Question 3 of 5
The nurse is caring for an adolescent with a five-year history of bulimia. A common clinical finding in the client with bulimia is:
Correct Answer: B
Rationale: Frequent vomiting in bulimia exposes teeth to stomach acid, leading to dental caries (tooth decay), a common clinical finding.
Question 4 of 5
The postpartum nurse should include which of the following instructions to breast-feeding mothers?
Correct Answer: C
Rationale: Limiting initial feeding times will only delay nipple soreness as well as the establishment of the letdown reflex, thus encouraging engorgement from clogged ducts and ductules. Soap should be avoided because it may be excessively drying, predisposing nipples to cracking. For optimal milk production, an additional 500 kcal over maintenance levels are needed daily. Lipase, not lactose, emulsifies the fat in breast milk, making it almost totally digestible by infants.

Correct Answer: A, C, D, F
Rationale: Lead exposure risks include stained glass work (
A), restoring old toys (
