Nursing Elites

1. The settings on a client's synchronized intermittent mandatory ventilation (SIMV) are respiratory rate 12 breaths/minute, tidal volume at 600 mL, FiO2 35%, and positive end-expiratory pressure (PEEP) 5 cm H2O. Which assessment finding necessitates immediate intervention by the nurse?

• A. Bilateral crackles in the lung bases.
• B. Low-pressure indicator alarm.
• C. Oxygen saturation of 91%.
• D. Respiratory rate of 18 breaths/minute.

Correct answer: B

Rationale: A low-pressure alarm may indicate a disconnection or leak in the system, which needs immediate intervention. Bilateral crackles in the lung bases may indicate fluid overload but do not require immediate intervention in this case. An oxygen saturation of 91% is concerning but not as urgent as a potential equipment issue. A respiratory rate of 18 breaths/minute is higher than the set rate but may not necessitate immediate intervention unless accompanied by other distress symptoms.

2. An infant has been diagnosed with cradle cap. What is the correct intervention to treat the scalp?

• A. Alcohol
• B. Mineral oil
• C. Calamine
• D. A&D ointment

Correct answer: B

Rationale: Cradle cap is a common condition in infants characterized by crusty patches on the scalp. The correct intervention to treat cradle cap is to apply mineral oil. Mineral oil helps soften the crusty patches, making it easier to remove them gently. Alcohol (Choice A) can be too harsh for an infant's sensitive skin and may cause irritation. Calamine (Choice C) is used to relieve itching associated with conditions like chickenpox or insect bites, not for treating cradle cap. A&D ointment (Choice D) is typically used for diaper rash and minor skin irritations, not for cradle cap.

3. A client with cancer is receiving chemotherapy with a known vesicant. The client's IV has been in place for 72 hours. The nurse determines that a new IV site cannot be obtained and leaves the present IV in place. What is the greatest clinical risk related to this situation?

• A. Impaired skin integrity
• B. Fluid volume excess
• C. Acute pain and anxiety
• D. Peripheral neurovascular dysfunction

Correct answer: A

Rationale: The correct answer is A: Impaired skin integrity. In this situation, the greatest clinical risk is related to impaired skin integrity due to the potential extravasation of the vesicant. Vesicants are substances that can cause severe tissue damage if they leak into the surrounding tissues. Choices B, C, and D are not the most significant risks in this scenario. Fluid volume excess, acute pain, and peripheral neurovascular dysfunction are not directly associated with leaving the IV in place with a known vesicant for an extended period.

4. An adult client who received partial-thickness and full-thickness burns over 40% of the body in a house fire is admitted to the inpatient burn unit.

• A. Normal Saline
• B. Lactated Ringer’s
• C. 5% Dextrose in water
• D. 0.45% Sodium Chloride

Correct answer: B

Rationale: In burn patients, Lactated Ringer's solution is preferred over other options as it helps in restoring fluid and electrolyte balance effectively. Lactated Ringer's contains electrolytes (sodium, potassium, calcium) that closely mimic the body's natural composition, making it a suitable choice for fluid resuscitation in burn injuries. Normal Saline (Choice A) lacks electrolytes like potassium and calcium, which are essential in burn management. 5% Dextrose in water (Choice C) is a hypotonic solution and is not the ideal choice for fluid resuscitation in burn patients. 0.45% Sodium Chloride (Choice D) is a hypotonic solution mainly used for conditions requiring free water replacement rather than volume expansion needed in burn injuries.

5. What pathophysiologic process is producing the symptoms of gout in a client with sudden onset of big toe joint pain and swelling?

• A. Deposition of crystals in the synovial space of the joints produces inflammation and irritation.
• B. Degeneration of joint cartilage causing inflammation.
• C. Infection of the joint space leading to inflammation.
• D. Increased synovial fluid causing joint swelling and pain.

Correct answer: A

Rationale: The correct answer is A. Gout is characterized by the deposition of uric acid crystals in the synovial fluid of joints, which triggers inflammation and pain. This process is known as crystal-induced arthritis. Choice B is incorrect as gout does not involve degeneration of joint cartilage. Choice C is incorrect as gout is not caused by an infection of the joint space. Choice D is incorrect as gout does not result from increased synovial fluid but rather from the deposition of uric acid crystals.
