1. In what sequence should the nurse prepare the dose of insulin for a client whose finger stick glucose is 210 mg/dl and is receiving a sliding scale dose of short-acting insulin before breakfast?
- A. Clean the vial's rubber stopper with an alcohol swab, withdraw the correct dose of insulin, and then inject air equal to the insulin dose into the vial.
- B. Inject air equal to the insulin dose into the vial, withdraw the correct dose of insulin, and then clean the vial's rubber stopper with an alcohol swab.
- C. Withdraw the correct dose of insulin, inject air equal to the insulin dose into the vial, and then clean the vial's rubber stopper with an alcohol swab.
- D. Clean the vial's rubber stopper with an alcohol swab, inject air equal to the insulin dose into the vial, and then withdraw the correct dose of insulin.
Correct answer: A
Rationale: The correct sequence for preparing a dose of insulin involves ensuring proper aseptic technique. First, clean the vial's rubber stopper with an alcohol swab to prevent contamination. Second, withdraw the correct dose of insulin to be administered. Lastly, inject air equal to the insulin dose into the vial to maintain proper pressure for withdrawing the medication. This sequence ensures the medication is prepared safely and accurately. Choice A is correct as it follows this sequence. Choices B, C, and D present incorrect sequences that may compromise patient safety by not following the correct aseptic technique. Choice B injects air into the vial before withdrawing insulin, which is incorrect. Choice C reverses the order of withdrawing insulin and injecting air. Choice D withdraws the insulin before injecting air, which can affect the pressure inside the vial and lead to inaccurate dosing.
2. A female client tells the clinic nurse that she has doubts about binge eating but cannot make herself vomit after meals. Which action by the nurse provides data to support the suspected diagnosis of bulimia?
- A. Ask the client to complete a food diary for the last 3 days
- B. Review the client’s lab data to determine her TSH, T3, and T4 levels
- C. Interview the client about her use of laxatives and diuretics
- D. Encourage the client to describe her daily exercise regimen
Correct answer: C
Rationale: Inquiring about laxative and diuretic use helps confirm bulimia as these are common behaviors associated with the disorder. Asking the client to complete a food diary (Choice A) may provide information on eating patterns but does not directly support the diagnosis of bulimia. Reviewing lab data (Choice B) for thyroid function is not specific to bulimia. Encouraging the client to describe her exercise regimen (Choice D) may be relevant for overall health assessment but does not specifically address bulimia symptoms.
3. A client diagnosed with a deep vein thrombus (DVT) followed by a diagnosis of pulmonary embolism (PE) is receiving heparin via an infusion pump at a rate of 1400 u/hour. The client tells the nurse, “I wish this medicine would hurry up and dissolve this clot in my lung so that I can go homeâ€. What response is best for the nurse to provide?
- A. Heparin prevents further clot formation, but your risk of bleeding needs to be monitored closely
- B. You seem to be concerned about the length of time it takes for Heparin to dissolve this clot
- C. Let me contact your healthcare provider to discuss the possibility of receiving IV heparin therapy at home
- D. Why are you so anxious to leave the hospital when you know you are not well enough yet?
Correct answer: A
Rationale: The correct response is A: 'Heparin prevents further clot formation, but your risk of bleeding needs to be monitored closely.' Heparin is an anticoagulant that prevents further clot formation, but it does not quickly dissolve existing clots. It is crucial for the nurse to educate the client about the purpose of heparin and the necessity for close monitoring of bleeding risks. Choice B is incorrect as it does not address the misunderstanding about heparin's mechanism of action. Choice C is incorrect as home administration of IV heparin therapy requires careful consideration and should not be suggested without a thorough assessment. Choice D is incorrect as it does not address the client's misconception about heparin's role in dissolving clots and instead focuses on the client's desire to leave the hospital.
4. An older male client with a history of type 1 diabetes has not felt well for the past few days and arrives at the clinic with abdominal cramping and vomiting. He is lethargic, moderately confused, and cannot remember when he took his last dose of insulin or ate last. What action should the nurse implement first?
- A. obtain a serum potassium level
- B. administer the client's usual dose of insulin
- C. assess pupillary response to light
- D. Start an intravenous (IV) infusion of normal saline
Correct answer: D
Rationale: Administering IV fluids is crucial to address potential dehydration and electrolyte imbalances, especially if the client is unable to provide a clear history. Starting an IV infusion of normal saline will help rehydrate the client and address any electrolyte imbalances, which are common in clients with diabetes experiencing symptoms like abdominal cramping and vomiting. Obtaining a serum potassium level can be important but is not the priority when the client is showing signs of dehydration and confusion. Administering insulin should only be done after addressing hydration and electrolyte status. Assessing pupillary response to light is not the most critical action in this situation compared to addressing dehydration and potential electrolyte imbalances.
5. A woman at 24-weeks gestation who has fever, body aches, and has been coughing for the last 5 days is sent to the hospital with admission prescriptions for H1N1 influenza. Which action has the highest priority?
- A. Administer Ringer's Lactate IV 125ml/8 hours
- B. Obtain specimens for cultures
- C. Assign a private room
- D. Monitor vital signs q4 hours
Correct answer: C
Rationale: Assigning a private room has the highest priority in this scenario. It helps prevent the spread of H1N1 influenza to other patients and protects both the patient and others from potential infection. Obtaining specimens for cultures and monitoring vital signs are important but do not address the immediate need to prevent the spread of the virus. Administering Ringer's Lactate IV is not the priority in this case as it does not directly address the infectious nature of the condition.
