Critical Care Nursing Practice Questions Questions
Question 1 of 5
The nurse is caring for a 48-year-old patient who is intubated and on a ventilator following extensive abdominal surgery. Although the patient is respo nsive, the nurse is not able to read the patient’s lips as the patient attempts to mouth the words. Which of the following assessment tools would be the most appropriate for the nu rse to use when assessing the patient’s pain level? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A: The FACES scale. This scale uses facial expressions to assess pain, making it suitable for a patient who is unable to verbalize. The nurse can show the patient a series of faces depicting varying levels of pain and ask them to point to the one that best represents their pain level. This method is non-verbal and easy for patients to understand. The other choices are incorrect: B: The Pain Intensity Scale requires the patient to rate their pain on a numerical scale, which may be difficult for a non-verbal patient. C: The PQRST method is a mnemonic for assessing pain characteristics (provocation, quality, region, severity, timing), but it requires patient communication. D: The Visual Analogue Scale involves marking a point on a line to indicate pain intensity, which is not suitable for a non-verbal patient.
Question 2 of 5
When it is noted that a patient’s endotracheal tube is not se cured tightened, he respiratory care practitioner assists the nurse in taping the tube. After the tu be is retaped, the nurse auscultates the patient’s lungs and notes that the breath sounds over the left lung fields are absent. The nurse suspects is the cause of this finding?
Correct Answer: A
Rationale: The correct answer is A: The endotracheal tube is in the right mainstem bronchus. When the endotracheal tube is not secured properly and is retaped, there is a possibility that it may have migrated into the right mainstem bronchus, leading to absent breath sounds in the left lung fields. This condition is known as endobronchial intubation. In such cases, ventilation primarily occurs in the right lung, resulting in decreased or absent breath sounds on the contralateral side. Choices B, C, and D are incorrect as they do not explain the absence of breath sounds over the left lung fields in this specific scenario.
Question 3 of 5
A patient is being mechanically ventilated in the synchronized intermittent mandatory ventilation mode at a rate of 4 breaths/min. Spontaneous reabsiprbi.rcaotmio/tensst are 12 breaths/min. After receiving a dose of morphine sulfate, respirations decrease to 4 breaths/min. Which acid-base disturbance will likely occur?
Correct Answer: D
Rationale: The correct answer is D (Respiratory alkalosis). Morphine sulfate can cause respiratory depression, leading to decreased respiratory rate. In this case, the patient's breaths decrease from 12 to 4 breaths/min, indicating hypoventilation. With decreased ventilation, there is less CO2 elimination, resulting in respiratory alkalosis. The other choices can be ruled out: A (Metabolic acidosis) and B (Metabolic alkalosis) are less likely caused by morphine sulfate, and C (Respiratory acidosis) is incorrect because the scenario describes hypoventilation, not hyperventilation.
Question 4 of 5
The nurse notes that the patient’s arterial blood gas levels indicate hypoxemia. The patient is not intubated and has a respiratory rate of 22 breaths/min. what is the nurse’s first intervention to relieve hypoxemia?
Correct Answer: C
Rationale: The correct answer is C: Provide for oxygen administration. The first intervention for hypoxemia is to increase oxygen levels to improve oxygen saturation in the blood. Oxygen administration can be achieved through various devices such as nasal cannula, face mask, or non-rebreather mask. This intervention helps to increase the oxygen supply to the patient's tissues and organs, addressing the underlying cause of hypoxemia. Calling for emergency intubation (choice A) is not the first step unless the patient's condition deteriorates. Obtaining an order for BiPAP (choice B) may be beneficial in some cases but is not the initial intervention for hypoxemia. Suctioning secretions (choice D) may be necessary if airway obstruction is present but is not the first step in addressing hypoxemia.
Question 5 of 5
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
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.
