1. A client with diabetes mellitus is being taught by a nurse about mixing regular and NPH insulin. Which of the following statements by the client indicates an understanding of the teaching?
- A. I should roll the NPH vial between my hands before drawing it up.
- B. I should draw up the NPH insulin before the regular insulin.
- C. I should inject air into the vial of regular insulin first.
- D. I should wait 10 minutes after mixing the insulin to inject it.
Correct answer: A
Rationale: The correct answer is A. Rolling the NPH vial between the hands before drawing it up ensures proper mixing of the insulin. Choice B is incorrect because regular insulin should be drawn up first to avoid contamination. Choice C is incorrect as injecting air into the vial of regular insulin is not necessary. Choice D is incorrect as there is no need to wait 10 minutes after mixing the insulin before injecting it.
2. A nurse on a medical-surgical unit is caring for a group of clients. The nurse should identify that which of the following clients is at risk for hypovolemia?
- A. A client who has nasogastric suctioning
- B. A client who has chronic constipation
- C. A client who has syndrome of inappropriate antidiuretic hormone
- D. A client who took a toxic dose of sodium bicarbonate antacids
Correct answer: A
Rationale: The correct answer is A. Nasogastric suctioning can lead to hypovolemia due to the loss of gastric fluids. Chronic constipation and syndrome of inappropriate antidiuretic hormone (SIADH) are not typically associated with hypovolemia. A toxic dose of sodium bicarbonate antacids may lead to metabolic alkalosis, not hypovolemia.
3. A male Native American presents to the clinic with complaints of frequent abdominal cramping and nausea. He states that he has chronic constipation and had not had a bowel movement in five days, despite trying several home remedies. Which intervention is most important for the nurse to implement?
- A. Evaluate the stool samples for the presence of blood
- B. Assess for the presence of an impaction
- C. Determine which home remedies were used
- D. Obtain a list of prescribed medications
Correct answer: B
Rationale: Assessing for impaction is crucial as it is a common cause of constipation and abdominal discomfort. In this scenario, the patient's symptoms of chronic constipation and no bowel movement for five days despite trying home remedies indicate a potential impaction that needs to be assessed. Evaluating stool samples for blood, determining the home remedies used, or obtaining a list of prescribed medications, while potentially relevant, are not as urgent as assessing for impaction in this situation.
4. A healthcare professional is planning to collect a liquid stool specimen from a client for ova and parasites. Inaccurate test results may result if the healthcare professional:
- A. Refrigerates the collected specimen
- B. Collects the specimen in a sterile container
- C. Delays the collection of the specimen
- D. Uses a non-contaminated collection container
Correct answer: A
Rationale: Refrigeration can kill the ova and parasites present in the stool specimen, leading to inaccurate test results. Storing the specimen in a cold environment can disrupt the integrity of the parasites and ova, affecting the accuracy of the test. Collecting the specimen in a sterile container (Choice B) is the correct procedure to prevent external contamination. Delaying the collection of the specimen (Choice C) may affect the freshness of the sample but does not directly impact the test results. Using a non-contaminated collection container (Choice D) is essential to maintain the sample's integrity but does not relate to the risk of killing ova and parasites through refrigeration.
5. The client is receiving discharge instructions for warfarin (Coumadin). Which statement by the client indicates a need for further teaching?
- A. I will avoid eating foods high in vitamin K.
- B. I will have my blood tested regularly to monitor my INR levels.
- C. I will take the medication at the same time every day.
- D. I will use a soft toothbrush to prevent bleeding gums.
Correct answer: A
Rationale: The correct answer is A. Clients taking warfarin need to be consistent with their vitamin K intake to maintain a balance in blood clotting. Avoiding foods high in vitamin K is essential as they can interfere with the medication's effectiveness. Choices B, C, and D are all correct statements regarding warfarin therapy. Regular blood testing to monitor INR levels ensures the medication is working effectively, taking the medication at the same time daily maintains a consistent level in the bloodstream, and using a soft toothbrush helps prevent gum bleeding due to warfarin's anticoagulant effects.
