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 in- verted T waves in leads II, III and AvF c) ST segment elevation and deeply in- vertedT waves in leadsV4-V6, I and aVL d) ST segment depression and T wave elevation in leads II, III and AvL When teaching a family member to per￾form an aspect of patient care, the nurse should understand that family mem- bers... a) learn best if shown a complex proce- dure all at once. b) are unaffected by the timing of teach￾ing. c) learn unrelated tasks first. d) learn best if they perceive a need to learn. Which may cause the development of fixed pupils? 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 seg- ment 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 seg- ment depression is indicative of ischemia or an NSTEMI. REF: Morton PG, Fontaine DK. 2018. Learn best if they percieve a need to learn; Family members learn best if they per- ceive 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 learn￾ing and is a waste of the family's and provider's time. Learners are goal-orient- ed and want to make a connection be￾tween 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 Hypothermia; Hypothermia may cause fixed pupils.

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 STAPHYLO- COCCUS 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 thera- py. d) Place the patient on strict isolation. A patient has heart failure secondary to ischemic cardiomyopathy and end-stage in fixed pupils. However, hypoxia may cause wide and fixed pupils due to mid- brain damage. Opiates may cause pin- point pupils, but they are not fixed.The olfactory nerve is responsible for the sense of smell.REF: Morton PG, Fontaine DK. 2018. Use of psychotropic drugs is a
