What is a device that delivers a fine spray of medication into the airways?

  • A. Nebulizer
  • B. Inhaler
  • C. Oxygen concentrator
  • D. Peak flow meter
Correct Answer: A

Rationale: The correct answer is A: Nebulizer. A nebulizer is a device that delivers medication in the form of a fine spray into the airways, making it easier for the patient to inhale the medication and reach the lungs. It is commonly used for treating respiratory conditions such as asthma and COPD. Inhalers (B) deliver medication in a different format, through a measured dose of medication in aerosol form. Oxygen concentrators (C) provide supplemental oxygen and do not deliver medication. Peak flow meters (D) are used to measure the peak expiratory flow rate and are not used to deliver medication.

The nurse is administering nitroglycerin IV to a client with chest pain. What is the most important parameter to monitor?

  • A. Blood pressure
  • B. Heart rate
  • C. Oxygen saturation
  • D. Respiratory rate
Correct Answer: A

Rationale: The correct answer is A: Blood pressure. When administering nitroglycerin IV for chest pain, monitoring blood pressure is crucial as it can drop significantly, leading to hypotension. This can cause further complications. Heart rate may increase initially due to vasodilation, but it's not the most important parameter. Oxygen saturation and respiratory rate are also important but monitoring blood pressure takes precedence in this situation.

On what basis would the nurse suspect an MI?

  • A. He has pale, cool, clammy skin
  • B. He reports nausea and vomited once at home
  • C. He says he is anxious and has a feeling of impending doom
  • D. He reports he has had no relief of the pain with rest or position change
Correct Answer: D

Rationale: Persistent pain despite rest suggests MI.

A patient with cardiogenic shock receives a nursing diagnosis of decreased cardiac output. With the appropriate interventions, the anticipated outcome is for the patient to achieve:

  • A. baseline activity level.
  • B. baseline cardiac function.
  • C. decreased afterload.
  • D. reduced anxiety.
Correct Answer: B

Rationale: Restoring baseline cardiac function is the goal in managing decreased cardiac output.

What is the pathophysiology of acute pulmonary edema?

  • A. Acute pulmonary edema occurs when there is a sudden increase in left ventricular end-diastolic pressure, leading to leakage of fluid into the alveoli and interstitial spaces in the lungs.
Correct Answer: C

Rationale: This fluid accumulation impairs gas exchange, causing severe respiratory distress.

The client on enoxaparin (Lovenox) is scheduled for surgery. What is the nurse's priority action?

  • A. Hold the enoxaparin and notify the healthcare provider.
  • B. Administer the enoxaparin as scheduled.
  • C. Administer vitamin K before the surgery.
  • D. Monitor the client's INR and proceed with surgery.
Correct Answer: A

Rationale: The correct answer is A: Hold the enoxaparin and notify the healthcare provider. Enoxaparin is an anticoagulant that increases the risk of bleeding during surgery. Holding it reduces this risk. Notifying the healthcare provider is crucial for further guidance. Administering enoxaparin (B) can lead to excessive bleeding. Administering vitamin K (C) is not indicated for enoxaparin therapy. Monitoring INR (D) is not appropriate for enoxaparin, which does not affect INR levels.
