Nursing Elites

1. A nurse is reviewing the ABG results of a client with chronic emphysema. Which result suggests the need for further treatment?

• A. PaO2 level of 89 mm Hg
• B. PaCO2 level of 55 mm Hg
• C. HCO3 level of 25 mEq/L
• D. pH level of 7.37

Correct answer: B

Rationale: The correct answer is B. A PaCO2 level of 55 mm Hg is elevated, indicating carbon dioxide retention, a common complication of emphysema that necessitates intervention. Elevated PaCO2 can lead to respiratory acidosis, reflecting inadequate ventilation. Choices A, C, and D are within normal ranges. A PaO2 level of 89 mm Hg is acceptable. An HCO3 level of 25 mEq/L falls within the normal range, suggesting adequate compensation. A pH level of 7.37 is also within the normal range, indicating the client's acid-base balance is maintained.

2. A nurse is discussing immunity with a client who has received an immunization. The nurse should identify that an immunization functions as part of which of the following types of immunity?

• A. Innate immunity
• B. Passive immunity
• C. Acquired immunity
• D. Natural immunity

Correct answer: C

Rationale: Immunizations provide acquired immunity. They work by introducing antigens into the body, which triggers the immune system to produce antibodies specific to that antigen. Choice A, 'Innate immunity,' refers to the natural defense mechanisms an organism is born with and does not involve immunizations. Choice B, 'Passive immunity,' is the transfer of pre-formed antibodies and does not involve immunizations. Choice D, 'Natural immunity,' is a general term that encompasses all immunity that is not acquired through deliberate immunization or passive transfer of antibodies.

3. A nurse is teaching a client with mild persistent asthma who has been prescribed montelukast. Which statement by the nurse is appropriate?

• A. This medication can be used during an acute asthma attack.
• B. This medication should be taken before exercise.
• C. You can take this medication for 10 days, then discontinue.
• D. This medication helps decrease swelling and mucus production.

Correct answer: D

Rationale: The correct answer is D: 'This medication helps decrease swelling and mucus production.' Montelukast is used for long-term asthma management as it helps reduce inflammation and mucus production in the airways. It is not appropriate for acute asthma attacks. Choice A is incorrect because montelukast is not a rescue medication for acute attacks. Choice B is incorrect because montelukast is not specifically taken before exercise. Choice C is incorrect because montelukast is usually taken regularly, not just for a short duration.

4. A nurse is preparing to administer an enteral tube feeding through an NG tube at 250 mL over 4 hr. The nurse should set the pump to deliver how many mL/hr?

• A. 60 mL/hr
• B. 62 mL/hr
• C. 63 mL/hr
• D. 65 mL/hr

Correct answer: C

Rationale: Calculation: 250 mL / 4 hours = 62.5 mL/hr, which should be rounded up to 63 mL/hr. This ensures the correct rate is set for continuous feeding. Choice A (60 mL/hr) is incorrect as it does not reflect the accurate calculation. Choice B (62 mL/hr) is close but does not round up to the nearest whole number as required. Choice D (65 mL/hr) is higher than the correct calculation and would deliver the feeding solution at a faster rate than prescribed.

5. What is the name of a legal document that instructs health care providers and family members about what life-sustaining treatment an individual wants if they are unable to make decisions?

• A. Do Not Resuscitate
• B. Informed consent
• C. Living will
• D. Durable power of attorney for health care

Correct answer: C

Rationale: The correct answer is C, 'Living will.' A living will is a legal document that outlines an individual's preferences for life-sustaining medical treatment if they become unable to make decisions. Choice A, 'Do Not Resuscitate,' specifically refers to a directive that instructs healthcare providers not to perform CPR. Choice B, 'Informed consent,' pertains to a patient's right to be informed about and consent to medical treatment. Choice D, 'Durable power of attorney for health care,' involves appointing someone to make healthcare decisions on behalf of an individual when they are unable to do so.
