Because a step-down cardiac unit is unusually busy, a nurse fails to obtain vital signs at 0200 hours for a client 2 days postoperative for a mitral valve re- placement. The client was stable when assessed at 0600 hours, so the nurse documents the electrocar- diogram monitor's heart rate in the client's medical record for both the 0400 and 0600 vital signs. The charge nurse supervising the nurse determines that the nurse's behavior was: SELECT ALL THAT APPLY. 1. the correct action because neither complications nor harmful effects occurred. 2. a legal issue because the nurse has fraudulently falsified documentation. 3. demonstrating beneficence because the nurse decided what was best for the client. 4. an ethical issue of veracity because the nurse has been untruthful regarding the client's care. 5. an ethical legal issue of confidentiality because the nurse disclosed incorrect information. 6. demonstrating distributive justice because the nurse decided other clients' needs were priority.

2.4

The CNA is a senior nursing student who has been administering medications and per- forming procedures during clinical experiences as a student nurse. The charge nurse supervising care on the telemetry unit determines that care is appropriate when the registered nurse (RN) working with the CNA delegates: SELECT ALL THAT APPLY. 1. administering acetaminophen (Tylenol®) to the client with an elevated temperature. 2. taking vital signs on the client newly admitted with a diagnosis of heart failure. 3. finishing the discharge instructions so the client with a new pacemaker implant can go home. 4. changing a client's chest tube dressing because it got wet when the water pitcher overturned. 5. providing a sponge bath for the client with the elevated temperature. 6. checking the lung sounds of the client whose chest tube drainage system was tipped over and then righted

2.5

A client diagnosed with class II heart failure according to the New York Heart Association Func- tional Classification has been taught about the initial treatment plan for this disease.

A client is hospitalized for heart failure secondary to alcohol-induced cardiomyopathy. The client is started on milrinone (Primacor®) and placed on a transplant waiting list. The client has been curt and verbally aggressive in expressing dissatisfaction with the med- ication orders, overall care, and the need for energy conservation. A nurse should interpret that the client's behavior is likely related to the client's: 1. denial of the illness. 2. reaction to milrinone (Primacor®). 3. fear of the diagnosis. 4. response to cerebral anoxia.

3

A nurse is assessing a client diagnosed with an anterior-lateral myocardial infarction (MI).

A client admitted to a telemetry unit with a diagnosis of Prinzmetal's angina, has the following medications ordered. Upon interpretation of the client's electro- cardiogram (ECG) rhythm, the nurse notes a prolonged PR interval of 0.32 second. Based on this information, which medication order should the nurse question administering to the client? 1. Isosorbide mononitrate (Imdur®) 20 mg oral daily upon awakening 2. Amlodipine (Norvasc®) 10 mg oral daily 3. Nitroglycerin (Nitrostat®) 0.4 mg sublingual prn for chest pain 4. Atenolol (Tenormin®) 50 mg oral daily.

A male client confides to a clinic nurse that he is no longer dyspneic after receiving his new St. Jude's heart valve. He wants to have a vasectomy so that he can enjoy sexual intercourse again without the fear of his wife becoming pregnant. What is the nurse's best response? 1. "That's probably a good idea. The life expectancy after heart valve replacement is 10 to 15 years." 2. "You seem relieved that the heart valve replacement was successful and that you can enjoy a normal life again." 3. "If you have cardiac symptoms such as dyspnea during sexual intercourse, you can take a nitroglycerin tablet before sexual activity to prevent symptoms." 4. "Be sure to inform the physician that you have an artificial heart valve so you are given antibiotics as a preventive measure before the procedure."
