- CORRECT ANSWER:

12 lead placement - CORRECT ANSWER:

A 45-year-old male postsurgical patient is on a ventilator in the critical care unit. He has been tolerating the ventilator well and has not required any sedation. He becomes tachycardic and hypertensive. His respiratory rate has increased to 28 breaths/min. The ventilator is set on synchronized intermittent mandatory ventilation (SIMV) at a rate of 10 breaths/min. The patient has been suctioned recently via his endotracheal tube, and his airway is clear. He responds appropriately to the nurse's commands. The nurse

should:

• assess the patient's level of pain.
• decrease the SIMV rate on the ventilator.
• provide sedation as ordered.

d. suction the patient again. - CORRECT ANSWER: a

A 65-year-old patient with a history of metastatic lung carcinoma has been unresponsive to chemotherapy. The medical team has determined that there are no additional treatments available that will prolong life or improve the quality of life in any meaningful way. Despite the poor prognosis, the patient continues to receive chemotherapy and full nutrition support. This is an example of what end-of-life concept?

• Medical futility
• Palliative care
• Terminal weaning

d. Withdrawal of treatment - CORRECT ANSWER: A

Medical futility is a situation in which therapy or interventions will not provide a foreseeable possibility of improvement in the patient's health status. 1 / 4

A 72-year-old woman is brought to the ED by her family. The family states that she's "just not herself." Her respirations are slightly labored, and her heart monitor shows sinus tachycardia (rate 110 beats/min) with frequent premature ventricular contractions (PVCs). She denies any chest pain, jaw pain, back discomfort, or nausea. Her troponin levels are elevated, and her 12-lead electrocardiogram (ECG) shows elevated ST segments in leads II, III, and aVF. The nurse knows that these symptoms are most likely associated with which diagnosis?

• Hypokalemia
• Non-Q wave MI
• Silent myocardial infarction

d. Unstable angina - CORRECT ANSWER: c

A definitive diagnosis of pulmonary embolism can be made by

• arterial blood gas (ABG) analysis.
• chest x-ray examination.
• pulmonary angiogram.

d. ventilation-perfusion scanning. - CORRECT ANSWER: c

A mode of pressure-targeted ventilation that provides positive pressure to decrease the workload of spontaneous breathing through the endotracheal tube is

• continuous positive airway pressure.
• positive end-expiratory pressure.
• pressure support ventilation.

d. T-piece adapter. - CORRECT ANSWER: C

Pressure support (PS) is a mode of ventilation in which the patient's spontaneous respiratory activity is augmented by the delivery of a preset amount of inspiratory positive pressure

A patient develops frequent ventricular ectopy. The nurse prepares to administer which drug?

• Adenosine 2 / 4

• Atropine
• Lidocaine

d. Magnesium - CORRECT ANSWER: c

Lidocaine is an antidysrhythmic drug that suppresses ventricular ectopic activity

A patient has been diagnosed with Marfan syndrome. What information does the nurse plan to teach the patient about this condition?

• It is an autosomal dominant inherited disorder of connective tissue.
• It is caused by a random genetic mutation and is not familial.
• There are no drugs that help control the cardiac symptoms of the disease.
• Contact sports are permitted if precautions against concussion are taken. -

CORRECT ANSWER: A

Marfan syndrome is an autosomal dominant inherited disorder of connective tissue with a definite familial pattern. Beta blockers and ACE inhibitors are commonly used to treat the condition. Contact sports and weight lifting are generally prohibited.

A patient has been successfully converted from ventricular tachycardia with a pulse to a sinus rhythm.Upon further assessment, it is noted that she is hypotensive. The appropriate treatment for her hypotension

may include:(Select all that apply.)

• adenosine.
• dopamine infusion.
• magnesium.
• normal saline infusion.

e. sodium bicarbonate. - CORRECT ANSWER: b,d

A patient is admitted to the critical care unit with bradycardia at a heart rate of 39 beats/min and frequent premature ventricular contractions. Upon assessment, you note that she is lethargic and has complained 3 / 4

of dizziness for the past 12 hours. Which of the following are acceptable treatments for symptomatic bradycardia? (Select all that apply.)

• Atropine
• Epinephrine
• Lidocaine

d. Transcutaneous pacemaker - CORRECT ANSWER: a,b,d

A patient is admitted to the progressive care unit with a diagnosis of community- acquired pneumonia. The patient has a history of chronic obstructive pulmonary disease and diabetes. A set of arterial blood gases obtained on admission without supplemental oxygen shows pH 7.35; PaCO2 55 mm Hg; bicarbonate 30 mEq/L; PaO2 65 mm Hg.

These blood gases reflect:

• hypoxemia and compensated metabolic alkalosis.
• hypoxemia and compensated respiratory acidosis.
• normal oxygenation and partly compensated metabolic alkalosis.
• normal oxygenation and uncompensated respiratory acidosis. - CORRECT

ANSWER: B

The PaO2 of 65 mm Hg is lower than normal range (80 to 100 mm Hg), indicating hypoxemia. The high PaCO2 indicates respiratory acidosis. The elevated bicarbonate indicates metabolic alkalosis. Because the pH is normal, the underlying acid-base alteration is compensated. Given the patient's history of chronic pulmonary disease and a pH that is at the lower end of normal range, it can be determined that this patient is hypoxemic with fully compensated respiratory acidosis.

A patient is admitted with an acute myocardial infarction (AMI). The nurse knows that an angiotensin-converting enzyme (ACE) inhibitor should be started within 24 hours to reduce the incidence of which process?

• Myocardial stunning
• Hibernating myocardium
• Myocardial remodeling

d. Tachycardia - CORRECT ANSWER: c

• / 4
