Extract:
Question 1 of 5
Two nurses are confirming the dose of an insulin infusion for a client in DKA. The current rate of the client's infusion is 13 mL/hr. At this institution, continuous insulin infusions are mixed with 75 units of insulin in 150 mL of normal saline. What dose (units/hour) is the client currently receiving? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 6.5
Rationale: Insulin concentration is 75 units/150 mL = 0.5 units/mL. At 13 mL/hr, the dose is 0.5 × 13 = 6.5 units/hr.
Question 2 of 5
The nurse suspects that the client hospitalized with severe ulcerative colitis, may be developing the complication of toxic megacolon. Which assessment finding supports these suspicions?
Correct Answer: C
Rationale: An enlarging abdominal girth indicates distension, a key sign of toxic megacolon due to colonic dilation. Tenesmus, hyperactive bowel sounds, and anal fissures are associated with ulcerative colitis or other conditions but are not specific to toxic megacolon.
Question 3 of 5
During an intake assessment, a client with antisocial personality disorder uses profanity, sexual orientation slurs, and threatens to spit at the nurse. What is the MOST appropriate statement or ask for the nurse to make about the client's behavior?
Correct Answer: D
Rationale: Acknowledging the client's emotions while setting clear boundaries promotes a safe environment. Confrontational, irrelevant, or defensive responses may escalate the situation or fail to address the behavior effectively.
Question 4 of 5
The nurse is leading a community-based discussion group on pharmacotherapy used in obesity. Which statement(s) made by the participants is/are correct? (SELECT ALL THAT APPLY)
Correct Answer: A,D
Rationale: Lifestyle changes should precede pharmacotherapy, and weight loss drugs typically affect absorption or appetite. Other statements are incorrect due to safety concerns, unrealistic expectations, or inappropriate duration.
Question 5 of 5
The nurse receives an order to administer ranitidine 300 mg IVPB over one hour. Ranitidine is available 300 mg in 100 mL NSS. The drip factor of the piggyback tubing is 15 gtts/mL. How should the nurse infuse the drug in drops/minute?
Correct Answer: 25
Rationale: Infusing 100 mL over 60 minutes with a 15 gtt/mL drip factor: (100 ÷ 60) × 15 = 1.6667 × 15 = 25 gtt/min.
