Nokea
A client has just been admitted to the emergency department with chest pain. Serum cardiac enzyme levels are drawn, and the results indicate an elevated serum creatine kinase (CK)-MB isoenzyme, troponin T, and troponin I. The nurse concludes that these results are compatible with what diagnosis?
- A. Stable angina
- B. Unstable angina
- C. Prinzmetal's angina
- D. New-onset myocardial infarction (MI)
Correct Answer: D
Rationale: Creatine kinase (CK)-MB isoenzyme is a sensitive indicator of myocardial damage. Levels begin to rise 3 to 6 hours after the onset of chest pain, peak at approximately 24 hours, and return to normal in about 3 days. Troponin is a regulatory protein found in striated muscle (skeletal and myocardial). Increased amounts of troponins are released into the bloodstream when an infarction causes damage to the myocardium. Troponin I is particularly sensitive to myocardial muscle injury; therefore, the client's results are compatible with new-onset MI. Options 1, 2, and 3 all refer to angina. These levels would not be elevated in angina.

A client who has experienced an acute kidney injury is prescribed a fluid restriction of 1500 mL per day. Which interventions will the nurse implement to assist the client in maintaining this restriction? Select all that apply.
- A. Removing the water pitcher from the bedside
- B. Using mouthwash with alcohol for mouth care
- C. Prohibiting beverages with sugar to minimize thirst
- D. Providing the client with lip balm to keep lips moist
- E. Offering the client ice chips at intervals during the day
Correct Answer: A,D,E
Rationale: The nurse can help the client maintain fluid restriction through a variety of means. The water pitcher should be removed from the bedside to aid in compliance. The use of ice chips and lip ointments is another intervention that may be helpful to the client on fluid restriction. Frequent mouth care is important; however, alcohol-based products should be avoided because they are drying to mucous membranes. Beverages that the client enjoys are provided and are not restricted based on sugar content.
The nurse has a prescription to administer amphotericin B intravenously to the client diagnosed with histoplasmosis. Which should the nurse specifically plan to implement during administration of the medication to minimize the client's risk for injury? Select all that apply.
- A. Monitor for hyperthermia.
- B. Monitor for an excessive urine output.
- C. Administer a concurrent fluid challenge.
- D. Assess the intravenous (IV) infusion site.
- E. Assess the chest and back for a red, itchy rash.
- F. Monitor the client's orientation to time, place, and person.
Correct Answer: A,D
Rationale: Amphotericin B is an antifungal medication and is a toxic medication, which can produce symptoms during administration such as chills, fever (hyperthermia), headache, vomiting, and impaired renal function (decreased urine output). The medication is also very irritating to the IV site, commonly causing thrombophlebitis. The nurse administering this medication monitors for these complications. Administering a concurrent fluid challenge is not necessary. A rash or disorientation is not specific to this medication.
The nurse is developing a care plan for a client experiencing urge urinary incontinence. Which interventions would be helpful for this type of incontinence? Select all that apply.
- A. Surgery
- B. Bladder retraining
- C. Scheduled toileting
- D. Dietary modifications
- E. Pelvic muscle exercises
- F. Intermittent catheterization
Correct Answer: B,C,D,E
Rationale: Urge incontinence is the involuntary passage of urine after a strong sense of the urgency to void. It is characterized by urinary urgency, often with frequency (more often than every 2 hours); bladder spasm or contraction; and voiding in either small amounts (less than 100 mL) or large amounts (greater than 500 mL). It can be caused by decreased bladder capacity, irritation of the bladder stretch receptors, infection, and alcohol or caffeine ingestion. Interventions to assist the client with urge incontinence include bladder retraining, scheduled toileting, dietary modifications such as eliminating alcohol and caffeine intake, and pelvic muscle exercises to strengthen the muscles. Surgery and urinary catheterization are invasive measures and will not assist in the treatment of urge incontinence.
A hepatitis B screen is performed on a postpartum client and the results indicate the presence of antigens in the maternal blood. Which intervention should the nurse anticipate to be prescribed for the neonate? Select all that apply.
- A. Obtaining serum liver enzymes
- B. Administering hepatitis vaccine
- C. Supporting breastfeeding every 5 hours
- D. Repeating hepatitis B screen in 1 week
- E. Administering hepatitis B immune globulin
- F. Administering antibiotics while hospitalized
Correct Answer: B,E
Rationale: A hepatitis B screen is performed to detect the presence of antigens in maternal blood. If antigens are present, the neonate should receive the hepatitis vaccine and hepatitis B immune globulin within 12 hours after birth. Obtaining serum liver enzymes, retesting the maternal blood in a week, breastfeeding every 5 hours, and administering antibiotics are inappropriate actions and would not decrease the chance of the neonate contracting the hepatitis B virus.
The nurse notes an isolated premature ventricular contraction (PVC) on the cardiac monitor of a client recovering from anesthesia. Which action should the nurse take?
- A. Prepare for defibrillation.
- B. Continue to monitor the rhythm.
- C. Prepare to administer lidocaine hydrochloride.
- D. Notify the primary health care provider immediately.
Correct Answer: B
Rationale: As an isolated occurrence, the PVC is not life-threatening. In this situation, the nurse should continue to monitor the client. Frequent PVCs, however, may be precursors of more life-threatening rhythms, such as ventricular tachycardia and ventricular fibrillation. If this occurs, the primary health care provider needs to be notified. Defibrillation is done to treat ventricular fibrillation. Lidocaine hydrochloride is not needed to treat isolated PVCs; it may be used to treat frequent PVCs in a client who is symptomatic and is experiencing decreased cardiac output.
