A nurse suspects a client who has myasthenia gravis is experiencing a myasthenic crisis. Which of the following interventions should the nurse take?
Administer an anticholinesterase medication.
Instruct the client to perform the pursed lip breathing.
Prepare to administer a vasoconstrictor.
Prepare the client for mechanical ventilation.
The Correct Answer is D
Choice A reason:
Administering an anticholinesterase medication is not the primary intervention during a myasthenic crisis. While these medications can improve muscle strength in myasthenia gravis, they are not sufficient in the event of a crisis.
Choice B reason:
Pursed lip breathing is a technique used to manage dyspnea but is not adequate for the acute management of a myasthenic crisis, which can involve respiratory muscle paralysis.
Choice C reason:
Vasoconstrictors are not used in the treatment of myasthenic crisis. This condition is not related to vascular issues but to neuromuscular transmission failure leading to respiratory failure.
Choice D reason:
Mechanical ventilation is the correct intervention as it provides the necessary respiratory support when the patient's respiratory muscles are too weak to maintain adequate ventilation.

Correct Answer is B
Explanation
A. Using simple language is helpful, but speaking in a childlike manner can be demeaning and may lower the client’s self-esteem. Communication should remain respectful and age-appropriate.
B. Incorporating nonverbal cues such as gestures, facial expressions, pictures, and written words supports understanding. Clients with aphasia often benefit from visual aids and other alternative communication strategies to enhance comprehension.
C. Raising the pitch of the voice does not improve comprehension in aphasia because the issue is related to language processing rather than hearing ability. A normal tone should be maintained unless the client has a hearing impairment.
D. Asking multiple-choice questions can sometimes assist with expressive aphasia; however, relying solely on this method may limit natural communication. The broader and more supportive approach is to incorporate nonverbal communication techniques.
Correct Answer is B
Explanation
Right-sided heart failure is a condition in which the right ventricle fails to pump blood effectively to the lungs, causing a backup of blood in the systemic circulation. This leads to increased pressure in the right atrium and the vena cava, which can be measured by the central venous pressure (CVP). A normal CVP is 2 to 6 mm Hg, but in right-sided heart failure, it can rise above 10 mm Hg. Symptoms of right-sided heart failure include peripheral edema, jugular venous distension, hepatomegaly, ascites, and weight gain.
a. Increased pulmonary artery wedge pressure (PAWP). This statement is incorrect because it describes a finding of left-sided heart failure, not right-sided heart failure. Left-sided heart failure is a condition in which the left ventricle fails to pump blood effectively to the systemic circulation, causing a backup of blood in the pulmonary circulation. This leads to increased pressure in the left atrium and the pulmonary capillaries, which can be measured by the pulmonary artery wedge pressure (PAWP). A normal PAWP is 6 to 12 mm Hg, but in left-sided heart failure, it can rise above 18 mm Hg. Symptoms of left-sided heart failure include dyspnea, orthopnea, paroxysmal nocturnal dyspnea, crackles in the lungs, and pink frothy sputum.
c. Decreased brain natriuretic peptide (BNP). This statement is incorrect because it describes a finding of normal or reduced cardiac function, not heart failure. Brain natriuretic peptide (BNP) is a hormone secreted by the cardiac cells in response to increased stretch and pressure in the ventricles. It acts as a diuretic and a vasodilator, lowering blood volume and blood pressure. BNP is used as a biomarker for diagnosing and monitoring heart failure, as it reflects the degree of ventricular dysfunction. A normal BNP level is less than 100 pg/mL, but in heart failure, it can rise above 400 pg/mL.
d. Decreased specific gravity. This statement is incorrect because it describes a finding of dilute urine, not concentrated urine. Specific gravity is a measure of the concentration of solutes in urine, reflecting the ability of the kidneys to regulate fluid balance. A normal specific gravity is 1.005 to 1.030, but it can vary depending on fluid intake and output, hydration status, and renal function. In right-sided heart failure, fluid retention and reduced renal perfusion can cause oliguria and increased specific gravity of urine.
