Acute kidney injury from postrenal etiology is caused by
- A. obstruction of the flow of urine.
- B. conditions that interfere with renal perfusion.
- C. hypovolemia or decreased cardiac output.
- D. conditions that act directly on functioning kidney tissue.
Correct Answer: A
Rationale: The correct answer is A because postrenal acute kidney injury is caused by obstruction of urine flow, leading to pressure build-up in the kidneys and subsequent damage. Obstructions can be due to conditions such as kidney stones, tumors, or enlarged prostate. Choices B, C, and D are incorrect as they relate to pre-renal and intrinsic renal causes of acute kidney injury, not specifically postrenal obstruction. B refers to decreased blood flow to the kidneys, C to low volume or poor heart function affecting kidney perfusion, and D to direct damage to kidney tissue, which do not characterize postrenal etiology.

Which patient should the nurse refer for hospice care?
- A. A 60-year-old with lymphoma whose children are unable to discuss issues related to dying.
- B. A 72-year-old with chronic severe pain due to spinal arthritis and vertebral collapse.
- C. A 28-year-old with AIDS-related dementia who needs palliative care and pain management.
- D. A 56-year-old with advanced liver failure whose family members can no longer provide care in the home.
Correct Answer: C
Rationale: The correct answer is C because the patient with AIDS-related dementia requires palliative care and pain management, which are key components of hospice care. This patient is likely in the terminal stage of their illness and would benefit from the comprehensive support provided by hospice services.
Choice A is incorrect because the patient's children's inability to discuss dying issues does not necessarily indicate a need for hospice care. Choice B is incorrect as chronic severe pain due to spinal arthritis is not a sole criterion for hospice referral. Choice D is incorrect as advanced liver failure alone does not automatically qualify a patient for hospice care.
The critical care unit environment is very stressful for patients, families, and staff. What nursing action is directed at reducing environmental stress?
- A. Constant expert evaluation of patient status
- B. Limiting visits to immediate family
- C. Bathing all patients during hours of sleep
- D. Maintaining a quiet environment during hours of sleep
Correct Answer: D
Rationale: The correct answer is D: Maintaining a quiet environment during hours of sleep. This action is directed at reducing environmental stress in the critical care unit because noise and disturbances during sleep can negatively impact patients' rest and recovery. By ensuring a quiet environment, patients can have uninterrupted sleep, which is crucial for healing.
Rationale:
1. Constant expert evaluation of patient status (A) may be important but does not directly address environmental stress.
2. Limiting visits to immediate family (B) may hinder patients' emotional support and can be stressful for families.
3. Bathing all patients during hours of sleep (C) may disrupt patients' rest and increase stress levels rather than reduce it.
assessment, the patient is restless, heart rate has increased to 110 beats/min, respirations are 36 breaths/min, and blood pressure is 156/98 mm Hg. The cardiac monitor shows sinaubsir bt.acocmh/ytecsat rdia with 10 premature ventricular contractions (PVCs) per minute. Pulmonary artery pressures are elevated. The nurse suctions the patient and obtains pink, frothy secretio ns. Loud crackles are audible throughout lung fields. The nurse notifies the physician, w ho orders an ABG analysis, electrolyte levels, and a portable chest x-ray study. How d oes the nurse interpret the following blood gas levels? pH 7.28 PaCO 46 mm Hg Bicarbonate 22 mEq/L PaO 58 mm Hg O saturation 88% 2
- A. Hypoxemia and compensated respiratory alkalosis
- B. Hypoxemia and uncompensated respiratory acidosis
- C. Normal arterial blood gas levels
- D. Normal oxygen level and partially compensated metabaobliribc.c aomci/dteosts is
Correct Answer: B
Rationale: The correct answer is B: Hypoxemia and uncompensated respiratory acidosis.
Step-by-step rationale:
1. pH is low (7.28), indicating acidosis.
2. PaCO2 is elevated (46 mm Hg), indicating respiratory acidosis.
3. PaO2 is low (58 mm Hg), indicating hypoxemia.
4. Bicarbonate is within normal range (22 mEq/L), suggesting no compensation for the acidosis.
5. Oxygen saturation is low (88%), supporting the presence of hypoxemia.
Summary:
A: Incorrect - pH is low, not indicating compensated alkalosis.
C: Incorrect - Various abnormalities in the blood gas levels are present.
D: Incorrect - There is hypoxemia and uncompensated acidosis, not metabolic alkalosis.
Noise in the critical care unit can have negative effects on the patient. Which of the following interventions assists in reducing noise levels in the criticala cbiarbr.ec osme/ttetisnt g? (Select all that apply.)
- A. Asking the family to bring in the patient’s i-Pod or other device with favorite music.
- B. Inviting the volunteer harpist to play on the unit on a re gular basis.
- C. Remodeling the unit to have two-patient rooms to facil itate nursing care.
- D. Remodeling the unit to install acoustical ceiling tiles.
Correct Answer: A
Rationale: Step 1: Bringing in the patient's i-Pod with favorite music can provide personalized, soothing sounds, reducing stress and anxiety for the patient.
Step 2: Familiar music can create a calming environment, distracting the patient from external noise.
Step 3: Listening to music may improve patient comfort and overall experience in the critical care unit.
Summary: Option A is correct as it directly addresses noise reduction by providing a personalized, calming environment for the patient. Options B, C, and D do not specifically target noise reduction but focus on other aspects of care or facility improvement.
The family of a terminally ill patient is concerned about administering increasing doses of opioids for pain management. What is the nurse’s best response?
- A. Increasing opioids may hasten death, so alternative methods should be considered.
- B. Opioids are necessary to manage pain effectively and improve quality of life.
- C. We will reduce the opioid dose to avoid dependency.
- D. You should consult with a pain specialist about reducing the medication.
Correct Answer: B
Rationale: The correct answer is B because opioids are essential for effective pain management in terminally ill patients, improving their quality of life. Alternative methods may not provide sufficient pain relief. Choice A is incorrect as opioids do not necessarily hasten death when used appropriately for pain control. Choice C is incorrect because reducing opioid dose may lead to inadequate pain management. Choice D is incorrect as consulting a pain specialist to reduce medication may not be appropriate for terminally ill patients needing effective pain relief.
