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: C

Rationale: Diarrhea is the most common complication of enteral therapy, often due to formula composition, administration rate, or bacterial contamination. Aspiration (A) is a serious but less common complication. Constipation (B) and muscle weakness (D) are not typically associated with enteral therapy.

Correct Answer: B

Rationale: SSRIs (e.g., sertraline) commonly cause weight gain and sexual dysfunction (e.g., delayed ejaculation), per patient reports-key for adherence. Drowsiness/coma are overdose risks, not common. Headache/nausea occur but fade. Dry mouth/urine retention are anticholinergic, not SSRI. These impact quality of life, needing emphasis.

Correct Answer: C

Rationale: The rights of medication administration include the right patient, right medication, right dose, right route, right time, and right documentation. However, "right attitude" is not one of the recognized rights of medication administration. While having a positive and professional attitude is important for healthcare providers, it is not specifically listed as a distinct right in medication administration protocols.

Correct Answer: C

Rationale: Oseltamivir treats influenza by inhibiting neuraminidase . This prevents viral release from infected cells, reducing spread. M2 blockade is amantadine's action. IMP dehydrogenase , reverse transcriptase , and DNA polymerase (E) are unrelated. Neuraminidase inhibition shortens his illness.

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.

Correct Answer: D

Rationale: The Human Genome Project enables pharmacogenomics, tailoring drugs to genetic profiles for better efficacy (e.g., CYP2D6 variants), not eliminating drugs. Standardized doses ignore genetics. Disease prevention via genes complements, not replaces, drugs. Individualized therapy leverages genomics, enhancing treatment precision.

Correct Answer: D

Rationale: Warfarin is an anticoagulant medication that works by inhibiting vitamin K-dependent clotting factors in the body. Overdosing on warfarin can lead to excessive bleeding due to the lack of functional clotting factors. To reverse the effects of warfarin overdose, Vitamin K is given because it helps the body restore the levels of clotting factors that were reduced by warfarin. Vitamin K promotes the synthesis of clotting factors II, VII, IX, and X, which allows the blood to clot effectively again. Therefore, in the case of a warfarin overdose, Vitamin K is the appropriate antidote to help reverse the anticoagulant effects.

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.
