Question 1 of 5
Which vacutainer tubes should be used when a requisition calls for blood to be drawn for an H&H and glucose test?
Correct Answer: D
Rationale: The correct answer is 'One green, one red.' An H&H test involves hemoglobin and hematocrit, which are components of a complete blood count and are typically drawn in a lavender tube. On the other hand, blood for glucose testing is collected in grey tubes.
Therefore, when drawing blood for both an H&H and glucose test, one green tube for glucose and one red tube for H&H should be used. The other choices are incorrect because light blue tubes are used for coagulation studies, lavender tubes are for complete blood counts, and green tubes are for chemistry tests like glucose, while grey tubes are specifically for glucose testing.
Question 2 of 5
To which of the following do the CDC Standard precautions recommendations apply?
Correct Answer: D
Rationale: The correct answer is 'All patients receiving care in hospitals.' Standard precautions apply to all patients in healthcare settings, regardless of their infection status. These recommendations include all body fluids except sweat, non-intact skin, and mucous membranes.
Choice A is incorrect as standard precautions are not limited to patients with diagnosed infections.
Choice B is incorrect as standard precautions extend beyond blood or body fluids with visible blood.
Choice C is incorrect as sweat is an exception to the body fluids covered under standard precautions.
Question 3 of 5
The nursing diagnosis is Risk for impaired skin integrity related to immobility and pressure secondary to pain and presence of a cast. Which of the following desired outcomes should the nurse include in the care plan?
Correct Answer: B
Rationale: The correct desired outcome for a nursing diagnosis of 'Risk for impaired skin integrity' is to ensure that the skin remains intact and without redness during the hospital stay. This outcome directly addresses the risk identified in the diagnosis. Option A focuses on addressing immobility, which is not the priority for this diagnosis. Option C deals with pain relief, which is a separate concern. Option D is an intervention involving pressure prevention through repositioning, rather than an outcome related to skin integrity.
Question 4 of 5
Which of the following tests would MOST LIKELY be performed on a patient who is being monitored for coagulation therapy?
Correct Answer: A
Rationale: The correct answer is A: PT/INR. Prothrombin times (PT/INR) are commonly used to monitor patients on Coumadin (warfarin) therapy, an anticoagulant that slows the blood's ability to clot. Monitoring PT/INR levels helps ensure the patient is receiving the appropriate dosage of Coumadin.
Choice B, CBC (Complete Blood Count), is a general test that provides information on red blood cells, white blood cells, and platelets but is not specific to monitoring coagulation therapy.
Choice C, PTT (Partial Thromboplastin Time), is another coagulation test but is not as commonly used for monitoring Coumadin therapy.
Choice D, WBC (White Blood Cell count), is unrelated to monitoring coagulation therapy and is used to assess immune system function.
Question 5 of 5
Which desired outcome written by the nurse is correctly written and measurable?
Correct Answer: B
Rationale: An outcome statement must describe the observable client behavior that should occur in response to the nursing interventions. It consists of a subject, action verb, conditions under which the behavior is to be performed, and the level at which the client will perform the desired behavior. Option B is correctly written and measurable as it includes all the required elements: subject (client), action verb (lose), conditions (within the next 2 weeks), and the level at which the behavior should occur (4 lbs.). Option A lacks the conditions and a specific level, making it not measurable. Option C is a nursing intervention rather than a client goal. Option D does not provide a specific level at which the client should perform the desired behavior, making it not measurable as well.
