CCRN Test Bank Exam Practice Questions

and Answers


Which 12-lead ECG changes should be expected in a patient with ACS involving the inferior wall?


a) ST segment elevation in leads II, III and all the precordial leads


b) ST segment elevation and deeply inverted T waves in leads II, III and AvF


c) ST segment elevation and deeply inverted T waves in leads V4-V6, I and aVL


d) ST segment depression and T wave elevation in leads II, III and AvL - ANSWER✔✔-Correct Answer: ST

segment elevation and deeply inverted T waves in leads II, III and AvF




An inferior wall MI is associated with changes in leads II, III and aVF. ST segment elevation in leads V4-V6

and aVL are associated with an anterolateral MI. ST elevation in leads II, III, and all of the precordial leads

are consistent with a lateral wall MI. ACS is not associated with changes in leads II, III and aVL. Leads I

and aVL are the lateral leads. ST segment depression is indicative of ischemia or an NSTEMI.

b) are unaffected by the timing of teaching.


c) learn unrelated tasks first.


d) learn best if they perceive a need to learn. - ANSWER✔✔-Learn best if they percieve a need to learn;


Family members learn best if they perceive a need to learn. This is consistent with adult learning theory.

Establishing a "need to know" is an important first step for optimal educational efforts. The timing of

education is important for an optimal outcome to be realized. Teaching unrelated tasks will not enhance

learning and is a waste of the family's and provider's time. Learners are goal-oriented and want to make

a connection between what they are being taught and the goal (skill or knowledge) needed to solve a

problem. If they recognize the relevance of the task, they are more likely to be successful


Which may cause the development of fixed pupils?




a) hyperoxia


b) olfactory damage


c) hypothermia


d) opiates - ANSWER✔✔-Hypothermia;




Hypothermia may cause fixed pupils. Hyperoxia (oxygen toxicity) does not result in fixed pupils. However,

hypoxia may cause wide and fixed pupils due to midbrain damage. Opiates may cause pinpoint pupils,

but they are not fixed. The olfactory nerve is responsible for the sense of smell.REF: Morton PG, Fontaine

DK. 2018.

Which places the older adult at greater risk for alcohol-induced disease? - ANSWER✔✔-Use of

psychotropic drugs is a risk factor for older adults developing alcohol-induced disease. This is due to the

synergetic effects of psychotropic drugs and alcohol. Alcohol enhances the sedative effects of frequently

used psychotropic drugs. Older adults have a slower metabolism, a smaller volume of body water, and a

decrease in lean body tissue associated with aging.


Following hip replacement surgery, an elderly patient with a history of diabetes, hepatic insufficiency and

alcohol abuse has a postoperative course complicated by the development of a STAPHYLOCOCCUS

infection at the surgical site. Which intervention has the highest priority? a) Anticipate a return to the

operating room.


b) Prepare the patient for wound closure.


c) Apply negative-pressure wound therapy.


d) Place the patient on strict isolation. - ANSWER✔✔-Anticipate a return to the operating room.




The patient has risk factors (elderly, diabetes, alcohol and liver disease) and signs ( Staph infection) of

necrotizing fasciitis. Necrotic tissue must be completely excised and explored to clean tissue and ensure

the infection does not directly inoculate bone tissue. Strict isolation is not required as necrotizing fasciitis

is not contagious. Negative-pressure wound therapy could be used once the wound has undergone

debridement of necrotic tissue. Local and systemic infection must be completely controlled before

wound closure is addressed.REF: Morton, P.G. & Fontaine, D.K. (2018).


A patient has heart failure secondary to ischemic cardiomyopathy and end-stage coronary artery disease.

Which agents would be the MOST beneficial? a) flecainide (Tambocor) and hydralazine (Apresoline)


b) verapamil (Calan) and spironolactone (Aldactone)
