The nurse assesses a patient who is admitted for an overdo se of sedatives. The nurse expects to find which acid-base alteration?
- A. Hyperventilation and respiratory acidosis
- B. Hypoventilation and respiratory acidosis
- C. Hypoventilation and respiratory alkalosis
- D. Respiratory acidosis and normal oxygen levels
Correct Answer: B
Rationale: The correct answer is B: Hypoventilation and respiratory acidosis. When a patient overdoses on sedatives, it can lead to respiratory depression causing hypoventilation. Hypoventilation results in retention of CO2, leading to respiratory acidosis. This is because the body is not effectively exhaling CO2, causing an increase in carbonic acid levels and a decrease in blood pH. The other choices are incorrect because hyperventilation would lead to respiratory alkalosis (Choice A), hypoventilation does not cause respiratory alkalosis (Choice C), and normal oxygen levels do not indicate the acid-base imbalance caused by sedative overdose (Choice D).

In calculating the glomerular filtration rate (GFR) results for women, the creatinine clearance is usually:
- A. the same as for men.
- B. greater than that for men.
- C. multiplied by 0.85
- D. multiplied by 1.15.
Correct Answer: C
Rationale: The correct answer is C: multiplied by 0.85. This is because women typically have lower muscle mass compared to men, resulting in lower creatinine production. Therefore, to adjust for this difference, the creatinine clearance for women is multiplied by 0.85. This correction factor helps to more accurately estimate the GFR in women.
Choices A and B are incorrect because the creatinine clearance for women is not the same as or greater than that for men due to the physiological differences in muscle mass. Choice D is also incorrect as multiplying by 1.15 would overestimate the GFR in women.
As part of nursing management of a critically ill patient, o rders are written to keep the head of the bed elevated at 30 degrees, awaken the patient from se dation each morning to assess readiness to wean from mechanical ventilation, and implement oral care protocols every 4 hours. These interventions are done as a group to reduce thabei rrbi.csokm o/tef svt entilator-associated pneumonia. This group of evidence-based interventions is often referred to using what term?
- A. Bundle of care.
- B. Clinical practice guideline.
- C. Patient safety goal.
- D. Quality improvement initiative.
Correct Answer: A
Rationale: The correct answer is A: Bundle of care. A bundle of care refers to a set of evidence-based interventions that, when implemented together, have been shown to improve patient outcomes. In this scenario, keeping the head of the bed elevated, daily awakening from sedation, and oral care protocols are bundled together to reduce the risk of ventilator-associated pneumonia. This approach is based on the idea that implementing multiple interventions simultaneously is more effective than individual interventions alone.
Choices B, C, and D are incorrect because:
B: Clinical practice guidelines provide recommendations for healthcare providers based on evidence but do not necessarily involve a group of interventions bundled together.
C: Patient safety goals are specific objectives aimed at improving patient safety outcomes, but they do not specifically refer to a group of interventions bundled together.
D: Quality improvement initiatives focus on improving processes and outcomes in healthcare settings but do not necessarily involve a group of interventions bundled together for a specific purpose like in this case.
A patient in the ICU is complaining that he is not sleeping well at night because of anxiety. Which of the following would be the most helpful intervention for the nurse to make?
- A. Provide the patient with a bath immediately following his first 90-minute REM sleep cycle.
- B. Increase the patients pain medication.
- C. Provide the patient with 5 minutes of effleurage and then minimize disruptions.
- D. Monitor the patients brain waves by polysomnography to determine his sleep pattern.
Correct Answer: C
Rationale: Rationale:
C: Providing the patient with 5 minutes of effleurage (gentle massage) and minimizing disruptions is the most helpful intervention. Effleurage can help reduce anxiety and promote relaxation, improving sleep quality. Minimizing disruptions creates a conducive environment for sleep.
A: Providing a bath after REM sleep may disrupt the patient's sleep cycle, worsening anxiety.
B: Increasing pain medication may not address the root cause of anxiety and could lead to dependency or side effects.
D: Monitoring brain waves with polysomnography is an invasive procedure not typically indicated for managing anxiety-related sleep issues.
The nurse is a member of a committee to design a critical care unit in a new building. Which design trend would best be implemented to facilitate famil y-centered care?
- A. Ensuring that the patient’s room is large enough to inc lude a sleeper sofa and storage for family members’ personal belongings.
- B. Including a diagnostic suite in close proximity to the u nit so that the patient does not have to travel far for testing.
- C. Incorporating a large waiting room on the top floor of athbierb .hcooms/pteistta l with a scenic view and amenities such as coffee and tea.
- D. Providing access to a scenic garden for meditation.
Correct Answer: A
Rationale: Correct Answer: A
Rationale:
1. Family-centered care promotes involvement of family members in patient care.
2. A sleeper sofa in the patient's room allows family members to stay overnight, enhancing support for the patient.
3. Storage for personal belongings ensures families can have essentials close by, increasing comfort and convenience.
4. These design elements facilitate family presence, communication, and participation in care, aligning with family-centered care principles.
Summary of Incorrect Choices:
B. Having a diagnostic suite nearby is convenient but not directly related to family-centered care principles.
C. A waiting room with amenities is beneficial but does not directly involve families in patient care.
D. Access to a garden for meditation is helpful for relaxation but does not emphasize family involvement in care.
Which statement about resuscitation is true?
- A. Family members should never be present during resusc itation.
- B. It is not necessary for a physician to write “do not resu scitate” orders in the chart if a patient has a healthcare surrogate.
- C. “Slow codes” are ethical and should be considered in f utile situations if advanced directives are not available.
- D. Withholding “extraordinary” resuscitation is legal anda ebtirhbi.ccoaml /tiefs ts pecified in advance directives and physician orders.
Correct Answer: D
Rationale: The correct answer is D because it accurately states that withholding "extraordinary" resuscitation is legal and should be based on specified criteria in advance directives and physician orders. This is in line with medical ethics and patient autonomy.
A is incorrect because family presence during resuscitation can be beneficial for emotional support and decision-making. B is incorrect as it is still necessary for a physician to document "do not resuscitate" orders even with a healthcare surrogate. C is incorrect as "slow codes" are not ethical and go against the principle of beneficence.
