a nurse is preparing to administer nafcillin (Nallpen) IM to a client who has an infection. which of the following should the nurse plan to take ? SATA select a 25 gauge, 1/2 inch needle admin the medication deeply into the ventrogluteal muscle ask the client about previous allergy to penicillin before adminstering antiobiotic Monitor the client 30 mins following the injection Tell the client to expect a temporary rash following the injection

A 25 gauge needle is too small for an IM ijection. the nurse should plan to use a 19-22 gaugle 1 1/2 needle to reach muscle. the nurse would be sure to inject deeply into a large muscle mass to avoid damaging nerves. the nurse would also be sure to ask about previous reactions to penicillin and monitor the client 30 mins after injections for any adverse effects like itching, redness, or rash.

a nurse is reviewing a clients laboratory findings to identify which antibiotic the provider may prescribe to treat the clients UTI. which of the following tests would provide this information? Gram stain Culture Sensitivity Specific gravity

A sensitivity lab will provide information on which antibiotic would be most effective in treating a specific organism. a gram stain determines whether the organism is gram positive or negative a culture determines the type of organism that may be causing the infection. A specific gravity determines dilution of urine.

A nurse is monitoring serum electrolytes for four OA who take digoxin and furosemide. Which of the following electrolyte values put the client at risk for digoxin toxicity? Calcium 9.2 Calcium 10.3 Potassium 3.4 Potassium 4.8

A side effect of furosemide is hypotension which can increase digoxin toxicity causing dysrrhythmias. The other values are within Norma range.

Amylin Mimetics- Pramlintide (Symlin); mimics the action of amylin and reduce postprandial glucose levels by decreasing gastric emptying time and inhibits glucagon secretion Can be used for both type I and II DM

Adverse effects include Nausea, hypoglycemia, and reaction at injection site. Contraindicated for clients w/ RF and those on dialysis. Insulin increases risk of hypoglycemia, conccurent use with meds that slows gastric emptying like opioids or slow food absortion like acarbose will further delay gastric emptying. Admin SQ prior to meals in the thigh or abd. keep unopened vials in frig do not freeze and opened vials at room temp for 28 days not in direct sunlight. do not mix medication w insulin in the same syringe.

Insulins - Used by all type I Diabetics and some type II diabetics lowers the blood sugar by promoting cellular uptake of glucose, converts glucose into glycogen, and drives potassium into cells w/ glucose.

ADEVERSE EFFECTS include HYPOGLYCEMIA (too much insulin); w/ abrupt onset SNS: tachycardia, palpitations, diaphoresis, shakiness. W/ gradual onset PNS: HA, tremors,drowsiness,weakness. Administer glucose: for conscious clients, 15 g of carbs (4 oz OJ, 2 oz grape juice, 8 oz milk or glucose tab) for client not fully conscious- high risk for aspiration give IV glucose or 1 mg of glucagon IM. Encourage client to wear medic alert bracelet. LIPOHYPERTROPHY: rotate sites and allow 1 inch between injection sites. 2 in away from the umbilicus if in abd MEDICATIONS/FOOD INTERACTIONS- Sulfonylureas, meglitinides, beta blockers, and alcohol cause hypoglycemia. concurrent use of thiazide diuretics and glucocorticoids raise blood sugar levels and can cause hyperglycemia. Beta blockers can mask SNS response to hypoglycemia making it hard to identify hypoglycemia.

HIV/AIDS

HIV is a retrovirus that must attach to a host cell in order to replicate. RNA is changed into DNA using the enzyme reverse transcriptase. Antiretroviral agents are used to treat HIV infections, it does not cure HIV or decrease the risk of passing the HIV infection to others. Antiretroviral agents may act by preventing the virus from entering the cells (fusion/entry inhibitors and CCr5 antagonists). Others act by inhibiting enzymes needed for HIV replication (nuceloside reverse transcriptase inhibitors; NRTIs, non nucleoside reverse transcriptase inhibitors NNRTIs, protease inhibitors, and integrase inhbitor. Highly active antiretroviral therapy (HAART) involves 3-4 HIV meds in combo w/ other antiretroviral meds to reduce med resistance, adverse effects, and dosages. HAART is an aggressive tx method using 3 or more different medications to reduce the amt of virus and increase CD4 counts. Also treat or prevent secondary infections such as pneumocystis pnemonia. Skipping doses or taking decreased dosages cause medication resistance and possible treatment failure.

the digoxin level of 0.25 is below the therapeutic range of 0.5 -2.0 ng/ mL. the nurse should anticipate an increase in the digoxin

a nurse is reinforcing teaching to a client who has a new prescription for digoxin (lanoxin). which of the following can indicate digoxin toxicity and should be reported to the provider? select ATA fatigue constipation anorexia rash diplopia

the nurse should monitor for fatigue, GI effects such as N/V/D and anorexia, and visual changes such as blurriness, diplopia, yellow-green or white halos around objects.

A nurse is caring for a client who is taking ritonavir (Norvir), a protease inhibitor, to treat HIV infection. For which of the following abnormalities in laboratory values should the nurse monitor? Increased TSH and T4 levels Decreased AST and ALT Hypoglycemia Hyperlipidemia

used for clients at risk for pancreatitis and elevated TGs; works by decreasing LDL and TGs levels Can cause GI distress and may be take w food, facial flushing, feeling of warmth, tingling of hands/feet, hyperglycemia, hepatotoxicity and hyperuricemia (monitor kidney function, BUN, creatinine, I/O, encouage 2-3 L fluids, admin allopurinol if uric acid elevated) Standard admin is TID w/ or after meals. dosage much larger when taken as vitamin supplement.

Fibrates gemifibrozil (Lopid) fenofibrate (Tricor)

used for clients who cannot lower TGs w/ TLC or other antilipemic meds); decrease in TGs levels and increase in HDLs Adverse effects- GI distress, gallstones (RUQ pain, fat intolerance, bloating), myopathy, and hepatotoxicity. Contraindicated in clients w/ liver disorders, severe renal impairment, and gallbladder disease. avoid concurrent use w/ statins- increase risk of myopathy and concurrent use of warfarin increase risk of bleeding (monitor PT and INR and report indications of bleeding)

Antibiotics affecting bacterial cell wall Vancomycin (Vancocin) Aztreonam (Azactam)- monobactum Fosfomycin (Monurol)

used for serious infections c/b methicillin- resistant Staphylococcus aureus, E. Coli, or Staphylococcus epidermidis and antibiotic associated pseudo membranous colitis c/b C Diff. Can cause hearing loss and increased risk when used w/ other ototoxic drugs (loop diuretics and aminoglycosides), infusion reactions (red man syndrome; rashes flushing tachycardia and hypotension) IV infusion site thrombophlebitis- redness swelling inflammation, and Renal toxicity- monitor I/O and renal function tests. contraindicated in those w/ corn or corn product allergy or previous reaction to vancomycin. IV dose may be adjusted according to creatinine clearance levels if renal insufficiency is present.

Antianginal Agent- ranolazone (Ranexa)

used in chronic stable angina in combo w/ amlodipine, b blocker, or organic nitrate; lowers cardiac oxygen demand thus improving activity tolerance and decreases pain. Adverse effects- QT prolongation and elevated B/P. Should avoid concurrent use w/ CYP3A4 inhibitors (grapefruit juice, HIV protease inhibitors, macrolide antibiotics, azole antifungals, and verapamil), Quinidine, and sotalol (Betapace). it can increase digoxin levels and simvastatin levels - monitor dig level and report muscle weakness.
