When administering medications, what safety precautions are needed with various routes? What safety precautions must the nurse practice consis- tently to avoid self-injury and exposure to blood-borne Answer: First check tube placement by aspirating gastric con- pathogens? With a client who refuses an important medication, what for a swishing sound over the gastric area). When a liquid formulation is not available, approaches or interventions might persuade the client to crush a tablet or empty a capsule into 15 to 30 mL of warm water take the medication? Note: Do not crush enteric-coated or sustained- cated if the medication were a vitamin supplement or a release products because this alters their rate of absorption and laxative? To administer, ﬂush the feeding tube with tap water, draw medication into a syringe, and slowly instill the medication into SELECTED REFERENCES the tube, then ﬂush the tube again. Preferably, give each med- ication separately and rinse the tube between medications.

Teach clients and family members how to weight, health–illness status, and lifestyle use prescription and OTC drugs safely and habits likely to inﬂuence drug effects. When indicated, teach clients about the use of prescription, over-the-counter (OTC), potential effects of herbal and dietary and social drugs as well as herbal and dietary supplements. Identify nondrug interventions to prevent or plements, provide or assist them in obtaining decrease the need for drug therapy. Describe major considerations in drug ther- and decrease hazards of drug therapy. Discuss guidelines for rational choices of drugs, function or critical illness. Critical Thinking Scenario You are making the ﬁrst home visit for an elderly client with arthritis and hypertension who is taking the following medications: Ibuprofen 800 mg every 4 hours Prednisone 5 mg daily Lasix 20 mg twice a day Captopril 25 mg twice a day Pepcid 20 mg at bedtime Look up each of these medications. What criteria will you use to determine therapeutic effects for each drug? Note any side effects that are likely for each drug and what assessment data will be important to collect.

Despite these contacts with physicians generic aciclovir 400 mg fast delivery antiviral home remedy, he had never had a sperm count cheap aciclovir 800 mg line antiviral meds for shingles. Apparently order aciclovir with mastercard quantum antiviral formula, her husband had been able to achieve full erection and penetration buy 800mg aciclovir with mastercard hiv infection graph. Chromosome counts were just becoming available, so it was no surprise that he had not had what we would now call a complete workup earlier in his life. She told me he grew extremely rapidly before the ﬁrst grade and continued to grow until he was around nine years old, when he stopped completely. Her husband had often commented how he went from being the tallest and largest of his class in school in his early life to being one of the shortest in his teens. The husband had developed male secondary sexual characteristics at a very early age—increase in facial hair, growth of his penis. The wife had few questions and was relieved to know her hus- band was doing all right with the operation. Tere were open books on every surface and wooden slide boxes stacked in between the books, journals, and papers. He and I knew each other from some shared conferences at the medical school. I told him all I wanted to know was whether it was testicle, ovary, or a combination. I could hear myself breathing fast around the eyepieces and sensed the urgency to arrive at a decision both accurately and quickly. I then repeated my little lecture about the crucial need to hide everything we found. The pathologist and I agreed to use generic The Woman Who Believed She Was a Man 45 terms. We would avoid any terms that hinted of female or uterus, including the term hysterectomy, which was the operation I had recommended. Tese were the days of paternalism, and we thought nothing of withholding such informa- tion. The surgeon, gynecolo- gist, and I huddled off to one side so none of the other team mem- bers would overhear us. I have always believed patients in operat- ing rooms can hear at some unconscious level, and this was one time I wanted to be sure the patient had no chance of overhearing anything at any level. I believed this patient had congenital adrenal hyperplasia, so-called virilizing adrenal hyperplasia; this meant simply that, before he was born, the adrenals made excessive male hormones (androgens). His fetal androgens, coming not from testicles but from the adrenals, caused the phallus (clitoris, in this case) to fuse with the urethra and form what appeared at birth to be a normal penis. The child was born with what appeared to be undescended testicles; there was no rea- son to presume otherwise in that era. The formation of the internal genitalia are not driven or af- fected by androgens but are directed by some signal from the chro- mosomes. Tus, they remained the normal female ovaries, fallo- pian tube, and uterus we saw in the abdomen. All of this embryology and endocrinology had just been worked out in detail in animals and was only now being applied to cases in humans. Tere was a beauty to the embryological story that had been discovered, so sequential and understandable. And like all hu- man systems, it could go awry—as it had in this patient.

Rofecoxib blocking those associated with protective effects on gastric (Vioxx) acts within 45 minutes and peaks in 2 to 3 hours. Thus, they produce less gastric irritation than aspirin is 87% protein bound and has a half-life of 17 hours. In addition, they are not associated with metabolized in the liver and excreted in urine and feces. CHAPTER 7 ANALGESIC–ANTIPYRETIC–ANTI-INFLAMMATORY AND RELATED DRUGS 109 Acetaminophen (also called APAP, an abbreviation for Drugs at a Glance: Drugs for Gout N-Acetyl-P-Aminophenol) is a nonprescription drug com- monly used as an aspirin substitute because it does not cause Routes and Dosage Ranges Generic/ nausea, vomiting, or GI bleeding, and it does not interfere Trade Name Adults Children with blood clotting.

The probable mechanism for in- 3-d interval between creased risk of hepatotoxicity in this population is that ethanol courses of therapy induces drug-metabolizing enzymes in the liver.
