When assessing a patient who is receiving a loop diuretic, the nurse looks for the manifestations of potassium deficiency, which would include what symptoms? (Select all that apply.)

Correct Answer: D

Rationale: Loop diuretics can cause potassium deficiency (hypokalemia), leading to symptoms such as muscle weakness. The other symptoms listed, including dyspnea, constipation, tinnitus, anorexia, and lethargy, are not typically associated with potassium deficiency.

Correct Answer: D

Rationale: Pain is a significant contributor to the debilitation of an individual during a course of chemotherapy. The side effects of chemotherapy often include pain, which can be caused by treatment procedures, side effects of medication, or the cancer itself. Pain can lead to decreased mobility, appetite, and overall quality of life, impacting the individual's ability to cope with treatment and recovery. Managing pain effectively is crucial in improving the patient's comfort and overall well-being during chemotherapy. While diarrhea, alopecia, and constipation are common side effects of chemotherapy, they do not typically contribute as significantly to the debilitation of an individual compared to pain.

Correct Answer: A

Rationale: Imipramine, a tricyclic antidepressant, is highly cardiotoxic in overdose, often causing fatal dysrhythmias due to sodium channel blockade, leading to widened QRS complexes and ventricular arrhythmias. The priority assessment must focus on cardiac status to detect life-threatening changes like tachycardia or arrhythmias, requiring immediate intervention such as sodium bicarbonate or cardioversion. Liver function and renal status may be affected long-term but aren't the acute priority in overdose. Neurological function , while impacted (e.g., seizures), is secondary to cardiac risks, as circulatory collapse poses the greatest immediate threat. The nurse's focus on cardiac monitoring aligns with toxicology protocols, ensuring rapid response to the most lethal complication, making choice A the critical assessment in this emergency scenario.

Correct Answer: C

Rationale: Neonates have an immature blood-brain barrier, increasing opioid penetration, not blocking it, so that's false. Spinal analgesia involves mu, delta, and kappa receptors, not just one type, making that false. Depressed CO2 response is the most reliable sign of opioid-induced respiratory depression, a true statement, reflecting medullary suppression. Tolerance to miosis develops minimally, unlike analgesia, so that's false. Addison's patients are hypersensitive to opioids due to cortisol lack. The CO2 response is a key monitoring parameter in opioid overdose.

Correct Answer: A

Rationale: Carvedilol is available orally and is used to treat hypertension as well as congestive heart failure and left ventricular dysfunction after a myocardial infarction. Sotalol is a nonselective beta-adrenergic blocking agent used to treat potentially life-threatening ventricular arrhythmias and to maintain normal sinus rhythm in patients with atrial fibrillation or flutter. Propranolol is a nonselective beta-adrenergic blocking agent used for treatment of hypertension, angina, idiopathic hypertrophic subaortic stenosis (IHSS) induced palpitations, angina and syncope, some cardiac arrhythmias induced by catecholamines or digoxin, pheochromocytoma; prevention of reinfarction after myocardial infarction; prophylaxis for migraine headache (which may be caused by vasodilation and is relieved by vasoconstriction, although the exact action is not clearly understood); prevention of stage fright (which is a sympathetic stress reaction to a particular situation); and treatment of essential tremors. Tamsulosin is used to treat benign prostatic hyperplasia and is an alpha1-selective adrenergic blocking agent.
