Answer and Explanation

The Correct Answer is {"A":{"answers":"B"},"B":{"answers":"A"},"C":{"answers":"B"},"D":{"answers":"A"},"E":{"answers":"A"},"F":{"answers":"B"},"G":{"answers":"C"}}

Metoprolol 5 mg every 2 to 3 min up to three doses

Nonessential: Metoprolol is a beta-blocker used to reduce heart rate and blood pressure. However, in this scenario, the client already has a history of irregular heart rate and is currently tachycardic. Starting metoprolol at this frequency and dose without knowing the client's response or stability could exacerbate their condition. Therefore, it is considered nonessential until further assessment and stabilization.

Oxygen at 2 L/min via nasal cannula

Anticipated: The client's oxygen saturation dropped to 89% at 1015 and improved to 92% with oxygen supplementation by 1200. Given the client's symptoms and fluctuating oxygen saturation, supplemental oxygen is necessary to ensure adequate tissue oxygenation and is anticipated to support respiratory function.

Draw electrolytes along with Hgb and Hct

Nonessential: While electrolyte levels (such as potassium) are important to monitor, they are not immediately critical in the management of acute myocardial infarction or unstable angina. They can be drawn later for comprehensive assessment but are not urgently needed in the acute phase of care.

Morphine 6 mg IV bolus every 3 hr as needed for pain

Anticipated: Morphine is indicated for managing severe pain, such as chest pain associated with myocardial infarction. The client reported significant chest pain (7/10 initially), and morphine is appropriate to alleviate discomfort and reduce myocardial oxygen demand.

Nitroglycerin 0.4 mg SL now may repeat every 5 min up to 3 doses

Anticipated: Nitroglycerin is a vasodilator that helps relieve chest pain associated with angina or myocardial infarction by dilating coronary arteries. Given the client's chest pain and the protocol for administering nitroglycerin, it is anticipated to be effective in managing symptoms and improving coronary blood flow.

Obtain daily weight

Nonessential: Daily weight monitoring is useful for assessing fluid status in some conditions, but it is not immediately necessary in the acute management of myocardial infarction or unstable angina unless there are signs of fluid overload or heart failure, which are not evident in this case.

Atropine 0.5 mg IV bolus every 5 min up to 2 mg

Contraindicated: Atropine is used to treat bradycardia (slow heart rate). However, the client in this scenario is tachycardic (rapid heart rate), and atropine would exacerbate this condition. Therefore, it is contraindicated and should not be administered.

Correct Answer is B

Explanation

B. The appropriate action for a nurse to take would be to check for air leaks in the system. This can be done by clamping the tubing momentarily to see if the bubbling stops, which would suggest the presence of a leak.

A The drainage system should always be kept below the level of the chest and should not be raised or emptied unless specifically indicated.

C. Emptying the collection chamber is typically unnecessary unless it is nearing full capacity. Continuous bubbling in the water seal chamber does not indicate that the collection chamber needs immediate emptying.

D. Squeezing the tubing can disrupt the functioning of the drainage system and is not recommended. Drainage should flow passively into the collection chamber without external manipulation.

A. Furosemide B. Desmopressin C. Epinephrine D. Nitroprusside

Correct Answer is B

Explanation

B. Desmopressin is a synthetic analog of vasopressin (antidiuretic hormone) that promotes water reabsorption in the kidneys, reducing urine production. It is used to treat conditions associated with excessive urination, such as diabetes insipidus or nocturnal enuresis. Since the client is experiencing excessive thirst and polyuria (excessive urine output), desmopressin would be appropriate to help reduce urine volume and manage fluid balance.

A Given the client's already high urine output, administering furosemide would further increase urine production, potentially exacerbating fluid loss and dehydration.

C. Epinephrine does not address the underlying issue of excessive thirst and polyuria related to brain injury and would not be used in this context.

D. Nitroprusside is a vasodilator that reduces blood pressure by relaxing smooth muscle in blood vessels. It is used to treat hypertensive emergencies. Nitroprusside is not relevant for addressing excessive thirst and polyuria due to brain injury.
