Question 1 of 9

What strategies are appropriate for preventing deep vein tharboirbm.cbomo/steisst (DVT) and pulmonary embolus (PE) in an at-risk patient? (Select all that apply.) WWW .THENURSINGMASTERY.COM

Correct Answer: A

Rationale: The correct answer is A: Graduated compression stockings. These stockings help prevent blood from pooling in the legs, reducing the risk of DVT and PE. They improve circulation and reduce venous stasis. Option B, heparin, is used for treatment, not prevention. Option C, sequential compression devices, help prevent DVT but are not as effective as compression stockings. Option D, strict bed rest, can actually increase the risk of DVT by reducing blood flow.

Question 2 of 9

A 22-year-old patient who experienced a near-drowning accident in a local pool, but now is awake and breathing spontaneously, is admitted for observation. Which assessment will be most important for the nurse to take during the observation period?

Correct Answer: C

Rationale: The correct answer is C: Auscultate breath sounds. After a near-drowning incident, the main concern is potential respiratory complications such as aspiration pneumonia or pulmonary edema. Auscultating breath sounds will help the nurse assess for any signs of respiratory distress or complications. This assessment is crucial for early detection and intervention. A: Auscultating heart sounds is important but not as crucial as assessing breath sounds in this scenario. B: Palpating peripheral pulses is important for circulation assessment but does not address the immediate concern of respiratory complications. D: Checking pupil reaction to light is more relevant for neurological assessment and not as critical as assessing breathing in this situation.

Question 3 of 9

The intensive care unit (ICU) nurse educator will determine that teaching arterial pressure monitoring to staff nurses has been effective when the nurse:

Correct Answer: B

Rationale: The correct answer is B because positioning the zero-reference stopcock line level with the hemostatic axis ensures accurate arterial pressure monitoring. Placing the stopcock at the hemostatic axis allows for correct measurement of blood pressure without any errors due to height differences. This positioning helps in obtaining precise and reliable readings. A: Balancing and calibrating the monitoring equipment every 2 hours is important for equipment maintenance but does not directly impact the accuracy of arterial pressure monitoring. C: Ensuring the patient is supine with the head of the bed flat is a standard position for arterial pressure monitoring but does not specifically address the correct positioning of the stopcock. D: Rechecking the location of the hemostatic axis when changing the patient's position is essential for maintaining accuracy, but it does not directly relate to the initial correct positioning of the stopcock.

Question 4 of 9

The nurse is caring for a patient who sustained a head injury and is unresponsive to painful stimuli. Which intervention is most appropriate while bathaibnirgb. ctohme/ tpesatt ient?

Correct Answer: B

Rationale: The correct answer is B: Because the patient is unconscious, complete care as quickly and quietly as possible. This is the most appropriate intervention as it prioritizes the patient's comfort and minimizes unnecessary stimulation. Performing care quickly reduces the time the patient is exposed to potentially uncomfortable procedures. Being quiet also helps create a calming environment for the patient, which is important for someone who is unresponsive. Explanation for other choices: A: Asking a family member to help and discussing family structure is not appropriate as it can be intrusive and may not be relevant or beneficial to the patient's care. C: Informing the patient of the day and time is unnecessary as the patient is unresponsive. Providing care is more crucial than updating the patient. D: Turning on the television is inappropriate as it introduces unnecessary noise and distraction, which can be overwhelming for an unresponsive patient.

Question 5 of 9

The nurse responds to a ventilator alarm and finds the patient lying in bed holding the endotracheal tube (ET). Which action should the nurse take next?

Correct Answer: D

Rationale: The correct action is D: Manually ventilate the patient with 100% oxygen. This is crucial to ensure adequate oxygenation and prevent hypoxia. Holding the ET tube can lead to extubation and airway compromise. Activating the rapid response team (A) may delay immediate intervention. Providing reassurance (B) is important but not the priority in this situation. Calling the health care provider (C) to reinsert the tube would also lead to a delay in providing essential respiratory support.

Question 6 of 9

Which acid-base disturbances commonly occurs with the hyperventilation and impaired gas exchange seen in severe exacerbation of asthma?

Correct Answer: D

Rationale: The correct answer is D: Respiratory alkalosis. Hyperventilation in severe asthma exacerbation leads to excessive removal of CO2, causing a decrease in carbonic acid levels, resulting in respiratory alkalosis. Metabolic acidosis (A) is not typically associated with hyperventilation. Metabolic alkalosis (B) is caused by excessive loss of acid or gain of bicarbonate, not by hyperventilation. Respiratory acidosis (C) is characterized by an increase in CO2 levels due to inadequate ventilation, which is the opposite of what occurs in severe asthma exacerbation.

Question 7 of 9

The constant noise of a ventilator, monitor alarms, and inf usion pumps predisposes the patient to what form of stress?

Correct Answer: D

Rationale: The correct answer is D: Sensory overload. Constant noise from medical equipment can overwhelm the patient's senses, leading to sensory overload. This can result in increased stress levels, difficulty concentrating, and overall discomfort. Anxiety (A) is related to worry and fear, but in this context, the primary stressor is sensory overload, not anxiety. Pain (B) is a physical sensation, not directly related to the sensory overload caused by noise. Powerlessness (C) refers to a lack of control or influence, which is not the primary form of stress induced by constant noise. Therefore, the correct choice is D as it directly correlates with the impact of the noise on the patient's sensory perception.

Question 8 of 9

When preparing to cool a patient who is to begin therapeutic hypothermia, which intervention will the nurse plan to do (select all that apply)?

Correct Answer: C

Rationale: Rationale: Continuous cardiac monitoring is crucial during therapeutic hypothermia to monitor the patient's cardiac rhythm and detect any arrhythmias promptly. This intervention allows for immediate intervention if any cardiac issues arise. Explanation of other choices: A: Assisting with endotracheal intubation may be necessary for airway management but is not directly related to cooling the patient for therapeutic hypothermia. B: Inserting an indwelling urinary catheter may be needed for urine output monitoring but is not a priority intervention for cooling the patient. D: Restraining the patient is unnecessary and not indicated for therapeutic hypothermia; it may cause unnecessary distress and should be avoided unless absolutely necessary for patient safety.
