A nurse is preparing to titrate morphine 6 mg via IV bolus to a client. The amount available is morphine 8 mg/mL. How many mL should the nurse administer per dose?
(Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.75"]
To calculate the volume of solution, use the formula:
mL = (desired dose in mg / available dose in mg) x 1 mL
Plug in the given values:
mL = (6 mg / 8 mg) x 1 mL
Simplify and solve:
mL = 0.75 x 1 mL
mL = 0.75 mL
Round to the nearest hundredth and add a leading zero if needed:
mL = 0.75 mL

Correct Answer is C
Explanation
Heparin is an anticoagulant that prevents the formation of new clots and the extension of existing clots. It is the drug of choice for treating acute pulmonary embolism, which is a life-threatening condition caused by a blood clot that travels to the lungs and blocks a pulmonary artery.
a) Dexamethasone is a corticosteroid that reduces inflammation and suppresses immune response. It is not indicated for treating pulmonary embolism, but it may be used for other pulmonary conditions, such as asthma or COPD.
b) Atropine is an anticholinergic that blocks the action of acetylcholine and increases heart rate and cardiac output. It is not indicated for treating pulmonary embolism, but it may be used for bradycardia or asystole.
d) Furosemide is a loop diuretic that increases urine output and reduces fluid volume and blood pressure. It is not indicated for treating pulmonary embolism, but it may be used for heart failure or edema.
Correct Answer is ["A","B","D"]
Explanation
These findings are expected to be assessed in a client who has emphysema, which is a type of chronic obstructive pulmonary disease (COPD) characterized by destruction and enlargement of alveoli, loss of elastic recoil, and air trapping. These changes impair gas exchange and oxygenation, leading to chronic hypoxia and hypercapnia.
a) Dyspnea, or difficulty breathing, is a common symptom of emphysema, as the client has reduced lung capacity and increased work of breathing. Dyspnea may be worse with exertion, stress, or infection, and may cause anxiety and fatigue. The nurse should monitor the client's respiratory rate, rhythm, depth, and effort, and provide oxygen therapy as prescribed.
b) Barrel chest, or increased anteroposterior diameter of the chest, is a physical sign of emphysema, as the client has chronic air trapping and hyperinflation of the lungs. Barrel chest may also cause kyphosis, or curvature of the spine, and reduced chest wall movement. The nurse should measure the client's chest circumference and observe for any deformities or asymmetry.
d) Clubbing of the fingers, or enlargement and rounding of the nail beds, is a late sign of emphysema, as the client has chronic hypoxia and tissue ischemia. Clubbing may also affect the toes and ears, and may indicate pulmonary or cardiac disease. The nurse should inspect the client's nails for shape, color, angle, and capillary refill.
c) Deep respirations are not expected to be assessed in a client who has emphysema, as the client has shallow and rapid breathing due to air trapping and reduced lung compliance. Deep respirations may indicate other conditions, such as metabolic acidosis or anxiety. The nurse should assess the client's arterial blood gas levels and provide reassurance and relaxation techniques as needed.
e) Bradycardia, or slow heart rate, is not expected to be assessed in a client who has emphysema, as the client has tachycardia or normal heart rate due to hypoxia and increased sympathetic stimulation. Bradycardia may indicate other conditions, such as medication side effects, vagal stimulation, or heart block. The nurse should monitor the client's pulse rate, rhythm, quality, and electrocardiogram as indicated.
