Question 1 of 5
In assessing a patient before administration of a cardiac glycoside, the nurse knows that which lab result can increase the toxicity of the drug?
Correct Answer: A
Rationale: Low potassium levels, such as the potassium level of 2.8 mEq/L presented in choice A, can increase the toxicity of cardiac glycosides like digoxin. Hypokalemia can potentiate the effects of cardiac glycosides on the heart muscle, leading to an increased risk of cardiac toxicity and arrhythmias. Therefore, monitoring and correcting potassium levels before administering cardiac glycosides is essential to reduce the risk of adverse effects.
Question 2 of 5
If a patient overdoses on Morphine, the nurse would give him as
Correct Answer: B
Rationale: Naloxone is an opioid receptor antagonist commonly used in cases of opioid overdose, such as with Morphine. When a patient overdoses on Morphine, they may experience respiratory depression, CNS depression, and sedation. Naloxone works by competitively binding to opioid receptors, displacing the opioid and reversing the effects of the overdose. It helps to quickly restore normal respiratory function and consciousness in patients who have ingested too much Morphine. Atropine, vitamin K, and physostigmine are not indicated for Morphine overdose.
Question 3 of 5
What patient could potentially take the drug Senna?
Correct Answer: B
Rationale: Senna is a stimulant laxative commonly used for the treatment of constipation. It is usually recommended for patients who have not passed stool in several days. Patients with conditions like eating disorders, hypersensitivity, anal fissures, or a history of hemorrhoids may have specific contraindications to using Senna, so they may not be suitable candidates for this medication.
Question 4 of 5
If a patient overdoses on Morphine, the nurse would give him ___________ as the
Correct Answer: B
Rationale: Naloxone is an opioid antagonist that is commonly used to treat opioid overdoses, including Morphine overdoses. When a patient overdoses on Morphine, they may experience respiratory depression, sedation, and decreased level of consciousness. Naloxone rapidly reverses these effects by competitively binding to opioid receptors in the body, displacing the Morphine and restoring normal respiratory function. In a clinical setting, naloxone is typically administered intravenously, intramuscularly, or subcutaneously by healthcare providers, such as nurses, to quickly counteract the effects of the opioid overdose. It is important to note that while naloxone helps reverse the effects of the opioid overdose, ongoing medical care and monitoring are still essential for the patient's recovery.
Question 5 of 5
What is Alprazolam therapeutic use?
Correct Answer: B
Rationale: Alprazolam is a medication commonly used to treat anxiety disorders. It belongs to a class of drugs called benzodiazepines, which work by enhancing the effects of a neurotransmitter in the brain called gamma-aminobutyric acid (GABA). This leads to a calming effect on the brain and central nervous system, helping to reduce feelings of anxiety and promote relaxation. Alprazolam is not indicated for preventing thrombus formation, decreasing the risk of stroke, or increasing urinary output.
