Your provider will obtain a signed consent from you prior to the completion of the CT scan.
A. You’ll need to let your doctor know if you have seafood allergies.
: Patients with seafood allergies may have a higher risk of allergic reactions to iodinated contrast media used in CT scans. However, this is not a definitive contraindication. The nurse should inform the patient to notify their healthcare provider about any known allergies, including seafood, as a precautionary measure. This allows the healthcare team to take necessary steps to prevent any adverse reactions, such as premedication with antihistamines or corticosteroids. Title:
B. Do not take your scheduled dose of Metformin 500 mg PO.
: Metformin is a common medication used to manage type II diabetes. When a patient is scheduled for a CT scan with IV contrast, it is crucial to withhold Metformin before the procedure. This is because the combination of Metformin and iodinated contrast can increase the risk of contrast-induced nephropathy (CIN) and lactic acidosis, a rare but serious condition. The general recommendation is to stop Metformin at the time of or prior to the procedure and withhold it for 48 hours after the procedure, resuming only after renal function has been re-evaluated and found to be normal. Title:
C. The procedure will be done at the bedside.
: CT scans, especially those requiring IV contrast, are typically performed in a radiology suite equipped with the necessary technology and medical personnel. Performing such a procedure at the bedside is uncommon and not standard practice due to the need for specialized equipment and immediate access to emergency care in case of adverse reactions. Therefore, this statement is incorrect. Title:
D. Take your Metformin as usual before the test.
: Taking Metformin as usual before the test is not recommended due to the risk of lactic acidosis when combined with iodinated contrast. As previously mentioned, Metformin should be withheld before and after the procedure until renal function is confirmed to be normal. This precaution helps to prevent any potential complications associated with the interaction between Metformin and the contrast agent.

Similar Questions
A client has been diagnosed with myxedema from long-standing hypothyroidism. What clinical manifestations of this disorder does the nurse recognize as progressing to myxedema coma? Select all that apply.
A. Hypertension
Hypertension is not typically associated with myxedema coma. Myxedema coma is characterized by severe hypothyroidism, which usually leads to low blood pressure (hypotension) rather than high blood pressure (hypertension). Therefore, hypertension is not a clinical manifestation that indicates progression to myxedema coma.
B. Restlessness
Restlessness is not a common symptom of myxedema coma. Patients with myxedema coma often present with lethargy, confusion, or even coma due to the severe slowing of metabolic processes. Restlessness is more commonly associated with hyperthyroidism or other conditions that increase metabolic activity.
C. Increased level of alertness
An increased level of alertness is contrary to the symptoms of myxedema coma. Myxedema coma typically presents with decreased mental status, including confusion, stupor, or coma. Therefore, an increased level of alertness would not be indicative of progression to myxedema coma.
D. Tachycardia
Tachycardia (rapid heart rate) is not a typical symptom of myxedema coma. Instead, myxedema coma is associated with bradycardia (slow heart rate) due to the severe hypothyroid state. Tachycardia is more commonly seen in hyperthyroid conditions.
E. Hypotension
Hypotension (low blood pressure) is a key clinical manifestation of myxedema coma. The severe hypothyroid state leads to decreased cardiac output and vascular resistance, resulting in hypotension. This is a critical sign that the nurse should recognize as indicative of progression to myxedema coma.
F. Bradycardia
Bradycardia (slow heart rate) is another hallmark of myxedema coma. The decreased metabolic rate in severe hypothyroidism leads to a reduced heart rate. Recognizing bradycardia is essential in identifying the progression to myxedema coma.
G. Hypoventilation
Hypoventilation (reduced breathing rate) is a significant symptom of myxedema coma. The severe hypothyroid state can lead to respiratory depression, resulting in hypoventilation. This can further exacerbate the patient’s condition and requires immediate medical attention.
H. Hyperventilation
Hyperventilation (increased breathing rate) is not associated with myxedema coma. Patients with myxedema coma typically experience hypoventilation due to the severe slowing of metabolic processes. Hyperventilation would be more indicative of conditions that increase metabolic activity or respiratory drive.

A client is admitted with bacterial meningitis. Which nursing intervention is the highest priority for this client?
A. Strict monitoring of hourly intake and output
Strict monitoring of hourly intake and output is important for managing fluid balance and detecting potential complications such as dehydration or fluid overload1. However, it is not the highest priority in the acute phase of bacterial meningitis. The primary concern is to monitor for signs of increased intracranial pressure (ICP) and neurological deterioration.
B. Managing pain through drug and non-drug methods
Managing pain through drug and non-drug methods is essential for patient comfort and overall well-being. Pain management can help reduce stress and improve the patient’s ability to rest and recover. However, it is not the highest priority compared to monitoring neurological status, which can provide early indications of complications such as increased ICP or seizures.
C. Assessing neurological status at least every 2 to 4 hours
Assessing neurological status at least every 2 to 4 hours is the highest priority for a client with bacterial meningitis. This frequent assessment helps detect early signs of neurological deterioration, increased ICP, and other complications. Early detection and intervention are crucial in preventing severe outcomes and improving the patient’s prognosis.
D. Decreasing environmental stimuli
Decreasing environmental stimuli is important to reduce stress and prevent exacerbation of symptoms such as headache and photophobia. While this intervention is beneficial, it is not as critical as frequent neurological assessments in the acute management of bacterial meningitis.

You are caring for a client in the ED with B/P 254/139 mm Hg. Which of the following actions would you take first?
A. Elevate the head of the client’s bed
Elevating the head of the client’s bed can help reduce blood pressure slightly by promoting venous return and decreasing intracranial pressure. However, this action alone is not sufficient to address the severe hypertension (254/139 mm Hg) the client is experiencing. Immediate medical intervention is required to prevent complications such as stroke, heart attack, or organ damage.
B. Contact the Rapid Response Team
Contacting the Rapid Response Team is the highest priority action. The Rapid Response Team is trained to handle critical situations and can provide immediate interventions to stabilize the client’s condition. Severe hypertension at this level requires urgent medical attention to prevent life-threatening complications. The team can administer medications to lower blood pressure quickly and monitor the client closely.
C. Tell the client to report vision changes
Telling the client to report vision changes is important because vision changes can indicate hypertensive retinopathy or increased intracranial pressure. However, this action is not the immediate priority. The client’s blood pressure needs to be controlled urgently to prevent further complications.
D. Insert a peripheral IV
Inserting a peripheral IV is necessary for administering medications and fluids. While this is an important step, it should follow the immediate action of contacting the Rapid Response Team. The team can then use the IV access to administer antihypertensive medications promptly.
E. Initiate seizure precautions
Initiating seizure precautions is important because severe hypertension can lead to seizures. However, this action is not the first priority. The primary focus should be on stabilizing the client’s blood pressure through immediate medical intervention.
