CCRN Test Bank EXAM QUESTIONS AND ANSWERS 100% SOLVED (Newest 2025) 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 - Correct Answers ✅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.

• learn unrelated tasks first.
• learn best if they perceive a need to learn. - Correct

Answers ✅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?

• hyperoxia
• olfactory damage
• hypothermia
• opiates - Correct Answers ✅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. 2 / 3

Morton PG, Fontaine DK. 2018.Which places the older adult at greater risk for alcohol- induced disease? - Correct Answers ✅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. - Correct Answers

✅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
