RN Nursing Care of Children Online Practice 2019 A
1. Physiologically, the child compensates for fluid volume losses by which mechanism?
- A. Inhibition of aldosterone secretion
- B. Hemoconcentration to reduce cardiac workload
- C. Fluid shift from interstitial space to intravascular space
- D. Vasodilation of peripheral arterioles to increase perfusion
Correct answer: C
Rationale: In response to dehydration, the body compensates by shifting fluids from the interstitial spaces to the intravascular space to maintain blood pressure and perfusion to vital organs. Hemoconcentration and vasoconstriction are other compensatory mechanisms but are less immediate.
2. The client makes which statement about lifestyle changes to reduce the development and progression of coronary artery disease that indicates the need for further teaching?
- A. “I will check my weight regularly for any gain or loss.”
- B. “I’ll make sure to take my high blood pressure medications.”
- C. “I am attending a smoking cessation class.”
- D. “As long as I exercise, stress at my job will not bother me.”
Correct answer: D
Rationale: The client stating, 'As long as I exercise, stress at my job will not bother me,' indicates a misunderstanding of the relationship between exercise and stress management. It is important to clarify that while exercise can help reduce stress, it may not eliminate all stressors, especially those related to work. Further teaching is needed to ensure the client understands the multifactorial approach required to address stress and its impact on coronary artery disease.
3. Which procedure is used to restore a normal heart rhythm in patients with arrhythmias, typically using electrical shocks?
- A. Cardioversion
- B. Defibrillation
- C. Ablation
- D. Angioplasty
Correct answer: A
Rationale: The correct answer is A: Cardioversion. Cardioversion is the procedure used to restore a normal heart rhythm in patients with arrhythmias by delivering controlled electrical shocks to the heart. Choice B, Defibrillation, is incorrect because defibrillation is used to treat life-threatening arrhythmias by delivering an unsynchronized high-energy shock to the heart. Choice C, Ablation, is incorrect as it involves destroying abnormal tissue that causes arrhythmias, not necessarily restoring normal heart rhythm. Choice D, Angioplasty, is unrelated to heart rhythm restoration and is a procedure to open blocked or narrowed blood vessels.
4. Is it a good idea for an athlete to eliminate all fat from his diet in order to stay lean?
- A. yes, because dietary fat is stored easily in fat cells and can't be used for energy
- B. no, because fats provide energy during prolonged exercise
- C. yes, because fat is stored under the skin and causes the body to overheat
- D. no, because excess fat is converted to glycogen and stored in the muscles
Correct answer: B
Rationale: Fat is an essential energy source during prolonged exercise, so eliminating it entirely from the diet is not advisable for athletes.
5. A client with breast cancer is receiving doxorubicin (Adriamycin). The nurse monitors the client closely for:
- A. Pulmonary fibrosis
- B. Cardiotoxicity
- C. Hepatotoxicity
- D. Nephrotoxicity
Correct answer: B
Rationale: Doxorubicin (Adriamycin) is an anthracycline chemotherapy agent commonly used to treat various cancers, including breast cancer. One of the significant side effects associated with doxorubicin is cardiotoxicity, which can lead to serious complications such as heart failure and arrhythmias. The risk of cardiotoxicity is dose-dependent, meaning that higher cumulative doses increase the likelihood of cardiac damage. Therefore, it is essential for nurses to monitor cardiac function closely through assessments such as echocardiograms or monitoring for signs and symptoms of heart failure, such as shortness of breath, fatigue, and edema.
