Nursing Elites

1. The nurse is caring for a client complaining of intense headaches with increasing pain for the past one month. An MRI is ordered. In reviewing the client's information, which piece of information is of concern?

• A. Allergy to shellfish
• B. Has a cardiac pacemaker
• C. A diabetic
• D. No IV access

Correct answer: B

Rationale: The correct answer is 'Has a cardiac pacemaker.' If a client with a cardiac pacemaker undergoes an MRI, the magnetic field can interfere with the pacemaker's function, leading to serious complications or even death. It is crucial to ensure that the pacemaker is compatible with MRI imaging or to consider alternative imaging modalities. The other choices, such as 'Allergy to shellfish,' 'A diabetic,' and 'No IV access,' are not direct contraindications for an MRI scan and do not pose the same level of risk as having a cardiac pacemaker.

2. When placing an IV line in a patient with active TB and HIV, which safety equipment should the nurse wear?

• A. Sterile gloves, mask, and goggles
• B. Surgical cap, gloves, mask, and proper shoewear
• C. Double gloves, gown, and mask
• D. Goggles, mask, gloves, and gown

Correct answer: D

Rationale: When dealing with a patient with active TB and HIV, the nurse should wear goggles, a mask, gloves, and a gown to protect themselves from potential exposure to infectious agents through respiratory secretions or blood. Surgical cap and proper shoewear are not specifically required for this procedure, making option B incorrect. Double gloving is not necessary in this scenario, hence option C is incorrect. Therefore, the correct choice is D as it includes all the essential protective equipment for this situation.

3. Which of the following arterial blood gas values indicates a patient may be experiencing a condition of metabolic acidosis?

• A. PaO2 90 mm Hg
• B. Bicarbonate 15 mEq/L
• C. CO2 47 mm Hg
• D. pH 7.34

Correct answer: B

Rationale: The correct answer is B: Bicarbonate 15 mEq/L. In metabolic acidosis, the bicarbonate levels are lower than normal. A bicarbonate value of 15 mEq/L indicates a deficit in the buffer system, contributing to the acidosis. Choices A, C, and D are incorrect. Choice A, PaO2 90 mm Hg, reflects oxygen partial pressure and is not directly related to metabolic acidosis. Choice C, CO2 47 mm Hg, represents carbon dioxide levels and is more indicative of respiratory status. Choice D, pH 7.34, falls within the normal range (7.35-7.45) and does not confirm metabolic acidosis.

4. A nurse at an outpatient clinic is returning phone calls that have been made to the clinic. Which of the following calls should have the highest priority for medical intervention?

• A. A home health patient reports, "I am starting to have a breakdown of my heels."?
• B. A patient that received an upper extremity cast yesterday reports, "I can't feel my fingers in my right hand today."?
• C. A young female reports, 'I think I sprained my ankle about 2 weeks ago.'
• D. A middle-aged patient reports, 'My knee is still hurting from the TKR.'

Correct answer: B

Rationale: The correct answer is the patient who received an upper extremity cast yesterday and reports not being able to feel their fingers in the right hand. This situation indicates a potential neurovascular issue that requires immediate attention to prevent complications. The other options are of lesser priority: A - Breakdown of the heels, while concerning, is not an acute issue that necessitates immediate intervention. C - An ankle sprain that occurred two weeks ago is now subacute and unlikely to be an urgent medical concern. D - Pain in the knee following a total knee replacement (TKR) is common in the early postoperative period and is not unexpected.

5. A client has been diagnosed with Disseminated Intravascular Coagulation (DIC) and transferred to the medical intensive care unit (ICU) following an acute bleeding episode. In the ICU, continuous Heparin drip therapy is initiated. Which of the following assessment findings indicates a positive response to Heparin therapy?

• A. increased platelet count
• B. increased fibrinogen
• C. decreased fibrin split products
• D. decreased bleeding

Correct answer: B

Rationale: In the context of DIC, effective Heparin therapy aims to halt the process of intravascular coagulation. One of the indicators of a positive response to Heparin therapy is an increase in fibrinogen levels. Heparin interferes with the conversion of fibrinogen to fibrin by thrombin. This interruption helps increase the availability of fibrinogen. While the platelet count may increase due to improved clotting, the primary focus of Heparin therapy is on fibrinogen. Fibrin split products are expected to decrease as the coagulation cascade is controlled. Although decreased bleeding is an ultimate goal, the immediate effect of Heparin is not directly on bleeding but on the coagulation process.
