Nursing Elites

1. A client with pneumonia is receiving oxygen therapy. Which of the following oxygen delivery devices should be used to deliver a precise oxygen concentration?

• A. Nasal cannula
• B. Simple face mask
• C. Venturi mask
• D. Non-rebreather mask

Correct answer: C

Rationale: A Venturi mask should be used to deliver a precise oxygen concentration to a client with pneumonia. Venturi masks are designed to deliver a specific oxygen concentration by mixing oxygen with room air in a precise ratio. This device is ideal for patients who require accurate oxygen delivery, such as those with chronic lung diseases. Nasal cannulas deliver a lower concentration of oxygen and are more suitable for patients with mild respiratory issues. Simple face masks and non-rebreather masks do not provide as precise control over the oxygen concentration as a Venturi mask.

2. After placing the patient back in bed, what should the nurse do next?

• A. Re-assess the patient.
• B. Complete an incident report.
• C. Notify the health care provider.
• D. Do nothing, no harm has occurred.

Correct answer: C

Rationale: After placing the patient back in bed, the nurse should notify the health care provider. This is important because the health care provider needs to be informed of the incident and assess the patient further to ensure no underlying injuries or issues exist. Re-assessing the patient is crucial but notifying the health care provider takes precedence in this situation. Completing an incident report is important for documentation purposes but not the immediate next step. Doing nothing is incorrect as there was an incident involving a fall that needs further evaluation.

3. What is the most appropriate method for preventing catheter-associated urinary tract infections (CAUTIs)?

• A. Insert a urinary catheter using clean gloves.
• B. Limit the duration of catheter use.
• C. Use a smaller size catheter to prevent trauma.
• D. Change the catheter tubing every 24 hours.

Correct answer: B

Rationale: The correct answer is B: Limit the duration of catheter use. Limiting the duration of catheterization is a crucial method for preventing catheter-associated urinary tract infections (CAUTIs). Prolonged catheter use increases the risk of introducing pathogens into the urinary tract, leading to infections. Using clean gloves for insertion (choice A) is important for preventing contamination but does not address the main cause of CAUTIs. Using a smaller size catheter (choice C) may help reduce trauma but does not directly prevent infections. Changing the catheter tubing every 24 hours (choice D) is not necessary unless clinically indicated, and it is not the most effective method for preventing CAUTIs.

4. A client with a new diagnosis of type 1 diabetes mellitus is being taught about self-administration of insulin by a nurse. Which of the following instructions should the nurse include?

• A. Store the current bottle of insulin at room temperature
• B. Massage the injection site after removing the needle
• C. Pull back on the plunger after injecting the insulin
• D. Use each syringe up to six times

Correct answer: A

Rationale: The correct answer is to store the current bottle of insulin at room temperature. Insulin should be stored this way to maintain its potency and effectiveness. Choice B is incorrect because massaging the injection site after removing the needle is not recommended practice and can cause bruising. Choice C is incorrect as pulling back on the plunger after injecting insulin can lead to injecting air bubbles into the tissue. Choice D is incorrect as syringes should not be reused multiple times due to the risk of contamination and inaccurate dosing.

5. A healthcare provider is reviewing the laboratory report of a client who is receiving heparin therapy for a deep vein thrombosis. Which of the following lab values indicates a therapeutic response to the therapy?

• A. PT of 12 seconds
• B. aPTT of 70 seconds
• C. Platelets of 150,000/mm3
• D. INR of 1.5

Correct answer: B

Rationale: An aPTT of 70 seconds is within the therapeutic range for a client receiving heparin therapy. The activated partial thromboplastin time (aPTT) is the most sensitive test to monitor heparin therapy. A therapeutic aPTT range for a client receiving heparin is usually 1.5 to 2.5 times the control value. Choices A, C, and D are not indicators of a therapeutic response to heparin therapy. PT measures the extrinsic pathway of coagulation and is not specific to monitoring heparin therapy. Platelet count is important to monitor for heparin-induced thrombocytopenia, but it does not indicate the therapeutic response to heparin therapy. INR is used to monitor warfarin therapy, not heparin therapy.
