1st degree AV block (1) - CORRECT ANSWER: Every impulse is conducted to the
ventricles, but duration of AV conduction is prolonged (the PR interval is prolonged, > 0,2 seconds) - usually asymptomatic, so check medications, continue to monitor
24-hour urine for free cortisol (1) - CORRECT ANSWER: Low-dose dexamethasone
suppression test used for baseline results of24-hout urine cortisol
2nd degree AV Block: Type 1 (1) - CORRECT ANSWER: Gradual lengthening of the PR interval due to prolonged AV conduction time. Eventually, atrial impulse is not conducted, and a QRS complex is blocked (missing). Almost always transient/well tolerated
2nd degree AV block: type 2 (1) - CORRECT ANSWER: P wave is not conducted, without progressive antecedent PR lengthening. Usually occurs when a block in one of the bundle branches is present - more serious, usually pacemaker time!
38 year old woman enters a community clinic. She is complaining of overwhelming fatigue that is not relieved by rest She is attending graduate school and is very sedentary. She is so exhausted that she has difficulty waking for classes and trouble concentrating when studying. Her face is puffy, and her skin is dry and pale. She is dressed inappropriately for warm weather.She also complains of generalized body aches and pains with frequent muscle cramps and constipation.
Vital signs:
BP 142/84
Heart rate 52 Respiratory rate 12 1 / 4
Temperature 36C No obvious irregularities are found in her cardiopulmonary assessment. Her TSH levels come back to 20.9 IU/L. She is diagnosed with hypothyroidism What can the nurse tell her about the treatment and follow up? - CORRECT ANSWER: Synthroid - need a lot of teaching because will need to take it every day for the rest of their life, side effects. Younger so probably won't have the same side effects as older adults but this is still important. Need to take at same time every day. Find out more about her specific symptoms and if there is anything we can do to help manage them (example constipation, trouble concentrating, how we can set her up for success with the things she needs to get done). Encourage activity but to the extent that she can tolerate until levels normalize. A lot of nursing is giving education but then allowing the patient to figure out how they are going to incorporate this education into their lives.Wording can also be important (example movement instead of exercise)

She is diagnosed with hypothyroidism What teaching will the nurse need to do with her before she leaves the clinic? - CORRECT ANSWER: Teaching on Synthroid. What to look for - it will take a while for levels to come up so don't expect to immediately feel better. Initial dosage may not be right so will require follow up and possibly dosage adjustment. We want them to come back in if the symptoms get worse. Also provide education about signs and symptoms of 2 / 4
hyperthyroidism because possibility of them taking too much thyroid hormone, may get shaky/sweaty

What do you notice about these findings? - CORRECT ANSWER: BP high, slightly
bradycardic, RR low end, temp is low especially for someone that is dressed excessively warm. With hypothyroidism, even though metabolism is decreased sometimes BP is high because of weakening heart muscle, not as efficient so works a bit harder, vessels tighten (what causes low HR and high BP), do sometimes also see low BP
3rd degree AV block (5) - CORRECT ANSWER: Form of AV dissociation in which no
impulses from the atria are conducted to the ventricles Atria are stimulated and contract independently of the ventricles Ventricular rhythm is an escape rhythm Ectopic pacemaker may be above or below the bifurcation of the bundle of His Pacemaker time!!!
