Nursing Elites

1. A healthcare professional is reviewing a patient's arterial blood gas values. Which of the following conditions apply under the following values? pH- 7.49 Bicarbonate ion 24 mEq/dl PaCO2 - 31 mmHg PaO2 - 52 mmHg FiO2 - 0.22

• A. respiratory acidosis
• B. respiratory alkalosis
• C. metabolic acidosis
• D. metabolic alkalosis

Correct answer: B

Rationale: The given blood gas values indicate respiratory alkalosis. A high pH and low PaCO2 level are consistent with respiratory alkalosis. In this scenario, no compensation for the alkalosis is noted, ruling out metabolic acidosis or alkalosis. Metabolic conditions would usually involve changes in bicarbonate levels, which remain within the normal range in this case.

2. What is the most common cause of acute renal failure?

• A. Shock
• B. Nephrotoxic drugs
• C. Enlarged prostate
• D. Diabetes

Correct answer: A

Rationale: The correct answer is 'Shock.' Acute renal failure is commonly caused by inadequate blood flow to the kidneys, which can occur in cases of shock. This leads to decreased kidney function and potential kidney damage. While nephrotoxic drugs can also cause acute renal failure, shock is the primary and most common cause. An enlarged prostate may lead to obstructive uropathy but is not the most prevalent cause of acute renal failure. Diabetes is typically associated with chronic kidney disease rather than acute renal failure.

3. A client with stress incontinence should be advised:

• A. to avoid relying solely on absorbent undergarments.
• B. that Kegel exercises might help.
• C. that effective surgical treatments are available.
• D. that behavioral therapy can be beneficial.

Correct answer: B

Rationale: Kegel exercises, which involve tightening and releasing the pelvic floor muscles, can be beneficial for stress incontinence by strengthening the muscles that control urination. Choice A is incorrect as it is important for the client to know that absorbent undergarments can be used as a temporary solution but do not address the underlying issue. Choice C is incorrect as while surgical treatments are available, they are usually considered when conservative treatments like exercises and behavioral therapy have not been successful. Choice D is incorrect as behavioral therapy can be beneficial in managing stress incontinence through lifestyle and dietary modifications, bladder training, and more, contrary to the statement that it is ineffective.

4. Which of the following microorganisms is easily transmitted from client to client on the hands of healthcare workers?

• A. mycobacterium tuberculosis
• B. clostridium tetani
• C. staphylococcus aureus
• D. human immunodeficiency virus

Correct answer: C

Rationale: The correct answer is staphylococcus aureus. Staphylococcus aureus microorganisms are ubiquitous and easily transmitted by healthcare workers who fail to conduct routine hand washing between clients. Staphylococcus aureus can reside on the skin and be transferred from one client to another if proper hand hygiene is not practiced. Mycobacterium tuberculosis is mainly transmitted through the airborne route, clostridium tetani is usually acquired through exposure to soil or dirt contaminated with tetanus spores, and human immunodeficiency virus is not easily transmitted through casual contact or on the hands of healthcare workers.

5. The nurse observes a nursing assistant performing AM care for a client with a new leg cast. Which action by the assistant will the nurse intervene?

• A. Lifting the affected leg with the palms of the hand
• B. Covering the affected leg with a blanket to avoid chills
• C. Placing plastic over the groin prior to bathing
• D. Elevating the cased leg on two pillows

Correct answer: B

Rationale: The correct answer is covering the affected leg with a blanket to avoid chills. Covering the leg with a blanket can prevent the evaporation of heat from the new cast, which can lead to skin irritation or discomfort. Lifting the affected leg with the palms of the hand is appropriate as it helps in providing support and prevents unnecessary pressure on the cast. Placing plastic over the groin prior to bathing is also acceptable to protect the area from getting wet. Elevating the cased leg on two pillows helps reduce swelling and promotes circulation, making it a suitable action.
