The critical care nurse knows that in critically ill patients, renal dysfunction
- A. is a very rare problem.
- B. affects nearly two thirds of patients.
- C. has a low mortality rate once renal replacement therapy has been initiated.
- D. has little effect on morbidity, mortality, or quality of life.
Correct Answer: B
Rationale: The correct answer is B. Renal dysfunction is common in critically ill patients due to various factors like sepsis, hypotension, and nephrotoxic medications. This affects nearly two thirds of patients, making it a significant issue in critical care. Choices A, C, and D are incorrect. A is wrong because renal dysfunction is not rare in critically ill patients. C is incorrect as renal replacement therapy does not guarantee low mortality rates. D is inaccurate as renal dysfunction can have a significant impact on morbidity, mortality, and quality of life in critically ill patients.

The nurse is caring for a patient who is mechanically ventilated. The nurse understands that what statement should be considered when determining apapbrirob.pcormia/ttees tn ursing interventions?
- A. Communication with intubated patients is often difficult.
- B. Controlled ventilation is the preferred mode for most p atients.
- C. Patients with chronic obstructive pulmonary disease w ean easily from mechanical ventilation.
- D. Wrist restraints are applied to all patients to avoid self- extubation.
Correct Answer: A
Rationale: The correct answer is A because communication with intubated patients is often challenging due to the presence of an artificial airway, which hinders speech. This understanding is crucial when determining appropriate nursing interventions to ensure effective patient care.
Choice B is incorrect because different patients may require different modes of ventilation based on their specific condition, and controlled ventilation may not always be the preferred mode for all patients.
Choice C is incorrect as patients with chronic obstructive pulmonary disease often have difficulty weaning from mechanical ventilation due to their underlying respiratory condition.
Choice D is incorrect as wrist restraints are not applied to all patients on mechanical ventilation unless absolutely necessary for safety concerns, such as preventing self-extubation.
The nurse is caring for a mechanically ventilated patient w ith a pulmonary artery catheter who is receiving continuous enteral tube feedings. When obtaining continuous hemodynamic monitoring measurements, what is the best nursing action?a birb.com/test
- A. Do not document hemodynamic values until the patient can be placed in the supine position.
- B. Level and zero reference the air-fluid interface of the t ransducer with the patient in the supine position and record hemodynamic values.
- C. Level and zero reference the air-fluid interface of the t ransducer with the patient’s head of bed elevated to 30 degrees and record hemodynamic values.
- D. Level and zero reference the air-fluid interface of the tarbainrbs.cdoumc/teers t with the patient supine in the side-lying position and record hemodynamic values.
Correct Answer: C
Rationale: Rationale: Option C is the correct answer because when caring for a patient with a pulmonary artery catheter receiving continuous enteral feedings, it is crucial to level and zero reference the transducer with the patient's head of bed elevated to 30 degrees. This position helps to ensure accurate hemodynamic measurements, as the head of bed elevation minimizes the impact of intra-abdominal pressure on the catheter readings. By referencing the transducer in this position, the nurse can obtain reliable and precise hemodynamic values.
Summary of Incorrect Choices:
A: This option is incorrect because delaying documentation until the patient is in the supine position can lead to inaccuracies in the hemodynamic readings due to changes in patient positioning.
B: Leveling and zero referencing the transducer with the patient in the supine position is not ideal as it does not account for the impact of intra-abdominal pressure on the catheter readings in patients receiving enteral feedings.
D: Leveling and zero referencing
Which interventions can the nurse use to facilitate communication with patients and families who are in the process of making decisions regarding end- of-life care options? (Select all that apply.)
- A. Communication of uniform messages from all healthca re team members
- B. An integrated plan of care that is developed collaborat ively by the patient, family, and healthcare team
- C. Facilitation of continuity of care through accurate shift -to-shift and transfer reports
- D. Limitation of time for families to express feelings in order to control family grief
Correct Answer: A
Rationale: The correct answer is A: Communication of uniform messages from all healthcare team members. This intervention is crucial to ensure consistency in information provided to patients and families, reducing confusion and enhancing trust. When all team members convey the same messages, it helps in clarifying options and facilitating decision-making.
Choices B and C are incorrect as they focus on care planning and continuity, which are important but not specifically related to facilitating communication in end-of-life care decisions. Choice D is incorrect as it suggests limiting time for families to express feelings, which can hinder effective communication and support during such a sensitive time.
Intrapulmonary shunting refers to what outcome?
- A. Alveoli that are not perfused.
- B. Blood that is shunted from the left side of the heart to t he right and causes heart failure.
- C. Blood that is shunted from the right side of the heart to the left without oxygenation.
- D. Shunting of blood supply to only one lung.
Correct Answer: C
Rationale: Step-by-step rationale for why choice C is correct:
1. Intrapulmonary shunting refers to blood bypassing the normal oxygenation process in the lungs.
2. Choice C describes blood being shunted from the right side of the heart (deoxygenated blood) to the left side without oxygenation, leading to systemic circulation without oxygenation.
3. Choices A, B, and D do not accurately describe intrapulmonary shunting as they focus on other concepts like alveolar perfusion, heart failure, and unilateral lung blood supply, respectively.
The nurse is caring for a patient receiving benzodiazepine intermittently. What is the best way to administer such drugs?
- A. Medicate around the clock, rather than as needed, to en sure constant sedation.
- B. Administer the medications through the feeding tube to prevent complications.
- C. Give the highest allowable dose for the greatest effect.
- D. Titrate to a predefined endpoint using a standard sedat ion scale.
Correct Answer: D
Rationale: The correct answer is D: Titrate to a predefined endpoint using a standard sedation scale. This approach ensures individualized dosing based on the patient's response, minimizing the risk of over-sedation or under-treatment. It allows for careful monitoring and adjustment of dosage to achieve the desired level of sedation while avoiding adverse effects.
A: Administering medication around the clock may lead to unnecessary sedation and increased risk of side effects.
B: Administering medications through a feeding tube is not recommended for benzodiazepines as it may affect absorption and increase the risk of complications.
C: Giving the highest allowable dose without considering individual response can result in excessive sedation and adverse effects.
