A nurse is caring for a client who has type 1 diabetes mellitus. The client reports that she is not feeling well. Which of the following findings should indicate to the nurse that the client is hypoglycemic? (Select all that apply.)

Rationale for Correct Choices

• Heart failure: The client has classic signs of heart failure, including S3 heart sound, bilateral crackles, lower extremity edema, elevated BNP, and cool extremities, indicating fluid overload and decreased cardiac output. Early identification allows timely interventions to prevent decompensation.

• Obtain a prescription for a diuretic: Diuretics reduce fluid retention, alleviate pulmonary congestion, and improve oxygenation. Administering a diuretic helps manage the client’s edema, dyspnea, and fatigue, reducing cardiac workload.

• Educate the client about sodium restriction : Limiting dietary sodium prevents further fluid retention and helps control blood pressure, reducing the risk of exacerbating heart failure symptoms and hospital readmission.

• Blood pressure: Monitoring BP is essential in heart failure to detect hypotension from decreased cardiac output or over-diuresis. Maintaining safe BP ensures adequate perfusion and guides treatment adjustments.

• Daily weight: Daily weights are a sensitive measure of fluid status. Rapid increases indicate fluid accumulation, allowing early interventions with diuretics or fluid management to prevent worsening heart failure.

Rationale for Incorrect Choices

• Aortic stenosis: Aortic stenosis primarily causes systolic murmur, angina, syncope, and sometimes heart failure over time. This client’s presentation is dominated by fluid overload and elevated BNP, with no auscultatory evidence of stenotic valve disease.

• Endocarditis : Endocarditis is associated with fever, positive blood cultures, heart murmurs, and skin lesions like Janeway lesions or Osler nodes. This client has no signs of infection, making endocarditis unlikely.

• Mitral stenosis : Mitral stenosis produces a diastolic murmur, pulmonary congestion, and sometimes atrial fibrillation. While some pulmonary signs may overlap with heart failure, this client lacks the characteristic murmur and risk factors for mitral stenosis.

• Prepare the client for cardioversion : Cardioversion is indicated for arrhythmias such as atrial fibrillation with rapid ventricular response. The client’s heart rhythm is regular, making this action unnecessary.

• Administer antibiotics as prescribed : Antibiotics are used for infections such as endocarditis or sepsis. This client has no fever, abnormal labs, or signs of systemic infection, so antibiotics are not indicated.

• Educate the client about valve replacement : Valve replacement education is relevant only if the client has significant valvular disease. This client’s data show no evidence of aortic or mitral valve pathology, so this action is not needed.

• Fever : Monitoring for fever is critical in infection or sepsis. Since the client’s temperature is normal, this is not an immediate concern.

• Blood cultures : Blood cultures identify bacteremia or endocarditis. The client has no infection indicators; therefore, this parameter is unnecessary.

• Skin lesions : Skin lesions such as Osler nodes or Janeway lesions indicate infective endocarditis. The client shows no such lesions, making monitoring irrelevant in this scenario.

Rationale:
A. Hypovolemia: Hypovolemia causes a decrease in PAWP due to reduced circulating blood volume and inadequate venous return to the heart. A low PAWP reflects decreased left ventricular preload, not an elevated value.

B. Hypotension: Hypotension alone does not directly increase PAWP. In fact, low blood pressure often accompanies decreased cardiac filling pressures. Elevated PAWP typically occurs with fluid overload or impaired ventricular function rather than simple hypotension.

C. Left ventricular failure: An elevated PAWP indicates increased left-sided heart pressures due to ineffective left ventricular pumping. Blood backs up into the pulmonary circulation, leading to pulmonary congestion and edema.

D. Cardiogenic shock: In cardiogenic shock, PAWP can be elevated due to impaired contractility, but it is accompanied by low cardiac output and hypotension. While related, the elevated PAWP in cardiogenic shock results from the underlying left ventricular failure, which is the primary cause of the pressure increase.
