Hydrochlorothiazide
"Hydrodiuril"- expected pharmacological action: thiazide diuretics work in the early distal convoluted tubule (DCT) to: 1) block the reabsorption of sodium and chloride, thus preventing the reabsorption of water at this site. 2) Promote diuresis when renal function is not impaired. Therapeutic Uses: Thiazide diuretics are often the medication of first choice for essential hypertension. They may be used for edema of mild to moderate heart failure and liver and kidney disease. Adverse effects & nursing interventions: 1) Dehydration= assess/monitor for signs of dehydration (dry mouth, increased thirst, minimal urine output, weight loss), monitor serum electrolytes and weight, report urine output less than 30 ml/h. stop medication and notify the provider. 2) Hypokalemia=monitor cardiac status and serum K levels, report a decrease in serum K (less than 3.5 mEq/L), teach client to consume foods high in K such as spinach and tomatoes, teach client to recognize signs of hypokalemia (nausea, vomiting, general weakness.) 3) hyperglycemia-monitor for an increase in blood glucose levels. Contraindications: Pregnancy risk Category B so avoid use during pregnancy and lactation. Digoxin toxicity can occur in the presence of hypokalemia so monitor cardiac status and K and Dig levels, and note that a potassium sparing diuretic can be used in conjunction with a thiazide diuretic to reduce the risk of hypokalemia. Antihypertensives have added hypotensive effects so closely monitor BP. Hyponatremia can lead to decrease in lithium carbonate excretion which may lead to toxicity so closely monitor lithium levels and dosage may need to be adjusted. NSAIDs reduce the diuretic effect so watch for reduced urine output and other signs of decreased effectiveness. Nursing administration: Can only be given orally, obtain baseline data to include orthostatic BP, weight, electrolytes, and location and extent of edema. Monitor K levels. Instruct client to take the medication first thing in the morning and if ordered twice a day be sure the second dose is taken by 2pm to prevent nocturia. Encourage consumption of foods high in K and maintain adequate fluid intake (1500 ml/day unless contraindicated), if GI upset occurs clients may take medication with or after meals, and note that alternate day dosing can decrease electrolyte imbalances. Evaluation: Decrease in BP, Decrease in edema, Increase in urine output.

Urinary retention • Advise clients to void every 4 hr. • Monitor I&O. • Assess the client's bladder for distention by palpating the lower abdomen area every 4 to 6 hr. Cough suppression • Advise clients to cough at regular intervals to prevent accumulation of secretions in the airway. • Auscultate the client's lungs for crackles, and instruct clients to increase intake of fluid to liquefy secretions. Sedation • Advise clients to avoid hazardous activities such as driving or operating heavy machinery. Biliary colic • Avoid giving morphine to clients who have a history of biliary colic.

Contraindicated with clients with hypersensitivity to nitrates. Contraindicated in clients with traumatic head injury because medication can increase intracranial pressure. Therapeutic Nursing Interventions: Treatment of angina attack - instruct the client to stop activity. The client should take dose of rapid-acting nitroglycerin immediately.

Heparin
parenteral anticoagulant Pharmacological action: prevent bleeding by inactivation of thrombin formation and factor Xa resulting in inhibition of the formation of fibrin. Therapeutic uses: In conditions necessitating prompt anticoagulant activity (evolving stroke, pulmonary embolism, massive deep venous thrombosis), as an adjunct for clients having open heart surgery or renal dialysis, as low-dose therapy for prophylaxis against postoperative venous thrombosis, in conjunction with thrombolytic therapy when treating an acute myocardial infarction, or treatment of disseminated intravascular coagulation. Administration: heparin cannot be absorbed by the intestinal tract so it must be given by subcutaneous injection or IV infusion. It can be given every 12 hours subQ or continuous or intermittent IV infusion. Adverse Effects/Nursing Interventions: 1)Hemorrhage secondary to heparin overdose= monitor VS, observe for signs of bleeding (increased heart rate, decreased BP, bruising, petechiae, hematomas, black tarry stool,) in the case of heparin overdose stop the heparin and administer protamine sulfate and avoid aspirin. Monitor activated partial thromboplastin time (aPTT) and keep this value at 1.5 to 2 times the baseline. 2) HIT (Heparin Induced Thrombocytopenia) as evidenced by a low platelet count and increased development of thrombi- mediated by antibody development (white clot syndrome)= monitor client's platelet count periodically throughout treatment especially in the first month, stop heparin if platelet count drops to less than 100,000/mm3. Nonheparin anticoagulants, such as lepirudin(Refludan) or argotroban(Acova), can be used as a substitute if anticoagulation is still needed. 3) Hypersensitivity reactions (chills, fever, urticarial)= administer a small test dose prior to the administration of heparin. 4) Toxicity/Overdose= administer protamine sulfate, which binds with heparin and forms a heparin-protamine complex that has no anticoagulant properties. Protamine sulfate should be administered slowly IV no faster than 20 mg/min or 50 m in 10 minutes. Contraindications: do not use in patients with low platelet count or uncontrolled bleeding, use cautiously with clients with hemophilia, increased capillary permeability, dissecting aneurysm, peptic ulcer disease, severe hypertension, hepatic or renal disease, or threatened abortion (miscarriage.) Heparin should not be used during or following surgeries of the eyes, brain, or spinal cord, lumbar puncture, or regional anesthesia. Administration: obtain baseline VS, CBC, platelet count, and hematocrit levels. Read label carefully since it is dispensed in units and in different concentrations. Check dosages with another nurse before administration. Use an infusion pump for continuous IV administration and monitor the rate of infusion every 30 to 60 minutes. Monitor aPTT every 4 or 6 hours until appropriate dose is determined, then monitor daily. For subQ injection use a 20-22 gauge needle to withdraw medication from the vial the change the needle to a smaller needle (25 or 26, ½ to 5/8 in length), administer deep subQ injections in the abdomen ensuring 2 inches from the umbilicus and do not aspirate and apply pressure for 1-2 minutes after injection and rotate and record injection sites. Monitor for signs of bleeding (bruising, bleeding gums, abdominal pain, nose bleeds, coffee ground emesis, tarry stools,) advise clients do not take NSAIDs, aspirin, or medications containing salicylates, and advise client to use electric razor for saving and a soft toothbrush. Evaluation: Client aPTT of 60-80 seconds and no development or no further development of venous thrombi or emboli.

Monitor CBC, serum calcium, albumin, and hepatic function.
Potassium
used to treat hypokalemia; potassium less than 3.5 mEq/L For clients receiving diuretics resulting in potassium loss, such as furosemide For clients with potassium loss due to excessive or prolonged vomiting, diarrhea, abuse of laxatives, intestinal drainage, and GI fistulas Side effects:GI distress and local GI ulceration, nausea, vomiting, diarrhea, abdominal discomfort, and esophagitis with oral administration Monitor clients receiving IV potassium for signs of hyperkalemia, such as bradycardia, hypotension, ECG changes. 1) Mix powdered formulations in at least 4 oz of liquid. 2) Advise clients to take potassium chloride with a glass of water or with a meal to reduce the risk of adverse GI effects. 3) Instruct clients not to crush extended-release tablets. 4)Instruct clients to notify the provider if they have difficulty swallowing the pills. IV administration 1)Never administer IV bolus. Rapid IV infusion can result in fatal hyperkalemia. 2)Use an IV infusion pump to control the infusion rate. 3)Dilute potassium and give no more than 40 mEq/L of IV solution to prevent vein irritation. 4)Give no faster than 10 mEq/hr. 5)Cardiac monitoring is indicated for serum potassium levels outside of normal parameters. 6)Assess the IV site for local irritation, phlebitis, and infiltration. Discontinue IV immediately if infiltration occurs. 7)Monitor the client's I&O to ensure an adequate urine output of at least 30 mL/hr.
