A nurse is providing teaching for a client who has a new diagnosis of angina pectoris. Which of the following information should the nurse include about anginal pain?
The pain usually lasts longer than 20 min.
The pain persists with rest and organic nitrates.
Pain can often be relieved by sitting up.
Exertion and anxiety can trigger the pain.
The Correct Answer is D
Choice A Reason: This is incorrect. Anginal pain usually lasts less than 20 min and subsides with rest or medication. Pain that lasts longer than 20 min may indicate a myocardial infarction.
Choice B Reason: This is incorrect. Anginal pain usually responds to rest and organic nitrates, such as nitroglycerin. Pain that does not improve with these measures may indicate unstable angina or a myocardial infarction.
Choice C Reason: This is incorrect. Anginal pain is not affected by the position of the client. Pain that is relieved by sitting up may indicate pericarditis or pleurisy.
Choice D Reason: This is correct. Anginal pain is caused by a temporary imbalance between the oxygen demand and supply of the myocardium. Factors that increase the oxygen demand, such as exertion, anxiety, cold, or heavy meals, can trigger anginal pain.

Correct Answer is D
Explanation
Choice A: Decreased specific gravity is not a finding of right-sided heart failure. Specific gravity is a measure of urine concentration, which can be affected by fluid intake, dehydration, kidney function, and diuretic use. Right-sided heart failure does not directly affect urine concentration, but it can cause fluid retention and edema in the body.
Choice B: Decreased brain natriuretic peptide (BNP) is not a finding of right-sided heart failure. BNP is a hormone that is released by the heart when it is stretched or overloaded. BNP helps to lower blood pressure and reduce fluid volume by increasing urine output and dilating blood vessels. BNP levels are elevated in both left-sided and right- sided heart failure, as the heart is under increased pressure and volume.
Choice C: Increased pulmonary artery wedge pressure (PAWP) is not a finding of right-sided heart failure. PAWP is a measure of the pressure in the left atrium, which reflects the pressure in the pulmonary capillaries. PAWP is elevated in left-sided heart failure, as the blood backs up in the lungs due to impaired left ventricular function. PAWP is normal or low in right-sided heart failure, as the blood backs up in the systemic circulation due to impaired right ventricular function.
Choice D: Elevated central venous pressure (CVP) is a finding of right-sided heart failure. CVP is a measure of the pressure in the right atrium, which reflects the pressure in the systemic venous system. CVP is elevated in right-sided heart failure, as the blood backs up in the body due to impaired right ventricular function. CVP can cause jugular venous distension, hepatomegaly, splenomegaly, ascites, and peripheral edema.
Correct Answer is A
Explanation
Choice A: Fatigue is a manifestation that the nurse should identify as indicating the client is hypokalemic. Hypokalemia is a condition in which the blood potassium level is lower than normal, usually due to excessive loss of potassium through urine, sweat, or vomiting. Potassium is an electrolyte that is essential for nerve and muscle function, especially for the heart. Hypokalemia can cause muscle weakness, cramps, and fatigue, as well as cardiac arrhythmias and dysrhythmias.
Choice B: Dyspnea is not a manifestation that the nurse should identify as indicating the client is hypokalemic. Dyspnea is a sensation of difficulty breathing or shortness of breath. Dyspnea can be caused by various conditions, such as asthma, chronic obstructive pulmonary disease (COPD), pneumonia, or pulmonary edema. Dyspnea is not directly related to hypokalemia, but it can be a sign of heart failure, which can cause fluid accumulation in the lungs and impair gas exchange.
Choice C: Oliguria is not a manifestation that the nurse should identify as indicating the client is hypokalemic. Oliguria is a reduced urine output, usually less than 400 mL per day or 30 mL per hour. Oliguria can be caused by various conditions, such as dehydration, kidney failure, urinary tract obstruction, or shock. Oliguria is not directly related to hypokalemia, but it can be a sign of kidney damage or impairment, which can affect electrolyte balance and fluid volume.
Choice D: Pitting edema is not a manifestation that the nurse should identify as indicating the client is hypokalemic. Pitting edema is a swelling of the tissues that leaves an indentation when pressed with a finger. Pitting edema can be caused by various conditions, such as venous insufficiency, lymphedema, liver cirrhosis, or malnutrition. Pitting edema is not directly related to hypokalemia, but it can be a sign of heart failure, which can cause fluid retention and overload in the body.
