Checking lung sounds

A client who has a cold is seen in the emergency department with an inability to void. Because the client has a history of benign prostatic hyperplasia, the nurse determines that the client should be questioned about the use of which medication?

Decongestants

Propantheline bromide is prescribed for a client with bladder spasms. Which disorder, if noted in the client's record, should alert the nurse to question the prescription for this medication?

Glaucoma

The nurse is providing dietary instructions to a client who has been prescribed cyclosporine. Which food item should the nurse instruct the client to exclude from the diet?

Grapefruit juice rationale: A compound present in grapefruit juice inhibits metabolism of cyclosporine through the cytochrome P450 system. As a result, consumption of grapefruit juice can raise cyclosporine levels by 50% to 100%, thereby greatly increasing the risk of toxicity. Red meats, orange juice, and green, leafy vegetables do not interact with the cytochrome P450 system. *Recall that grapefruit juice is contraindicated with many medications.

If taken with meals, it will help decrease the risk for gastrointestinal (GI) upset.

If taken with meals, it will help decrease the risk for gastrointestinal (GI) upset.

Trimethoprim-sulfamethoxazole is prescribed to be administered by intravenous infusion to a client with a recurrent urinary tract infection. How should the nurse administer this medication?

Over 60 to 90 minutes

A client with acute pyelonephritis who was started on antibiotic therapy 24 hours earlier is still complaining of burning with urination. The nurse should anticipate that the health care provider will prescribe which medication?

Phenazopyridine

A client is prescribed sulfamethoxazole for treatment of urinary tract infection. Identification of which other medication noted on the client's medical record requires further collaboration with the health care provider (HCP)?

Phenytoin

The nurse is planning to administer furosemide 40 mg by intravenous push (IVP) through an existing intravenous (IV) line. To deliver this medication safely, the nurse should perform which action?

Pinch the IV tubing above the injection port, and inject slowly over 1 to 2 minutes.

A client is receiving levofloxacin for treatment of urinary tract infection. Which finding warrants an immediate call to the health care provider (HCP)?

Prolonged QT interval on electrocardiogram

Nitrofurantoin is prescribed for the client. The nurse checks the client's record, knowing that this medication is contraindicated in which disorder?

Renal disease

A client with chronic kidney disease has a medication prescription for epoetin alfa. The nurse should plan to administer this medication by which method?

Subcutaneously

Thirty minutes after a meal

Oral bethanechol chloride is prescribed for the client. The nurse should instruct the client to take this medication at which time?

Two hours after meals

Tamsulosin hydrochloride is prescribed for a client. The nurse should suspect that this medication is prescribed to relieve which condition?

Urinary obstruction

Bethanechol chloride is prescribed for a client with urinary retention. Which disorder would be a contraindication to the administration of this medication?

Urinary strictures rationale: Bethanechol chloride can be hazardous to clients with urinary tract obstruction or weakness of the bladder wall. The medication has the ability to contract the bladder and thereby increase pressure within the urinary tract. Elevation of pressure within the urinary tract could damage or rupture the bladder in clients with these conditions.

Aluminum hydroxide is prescribed for a client with chronic kidney disease (CKD). The nurse should instruct the client to take this medication at what time?

With meals

The home health nurse is caring for a client who is taking probenecid. The client has been instructed to restrict the diet to low-purine foods. Which food item should the nurse instruct the client to avoid?

scallops

Oxybutynin

The nurse receives a call from a client concerned about eliminating brown-colored urine after taking nitrofurantoin for a urinary tract infection. The nurse should make which appropriate response?

"Continue taking the medication; the brown urine occurs and is not harmful." Rationale: Nitrofurantoin imparts a harmless brown color to the urine, and the medication should not be discontinued until the prescribed dose is completed. Magnesium hydroxide will not affect urine color. In addition, antacids should be avoided because they interfere with medication effectiveness.

A client with a urinary tract infection (UTI) is given a prescription for levofloxacin. The nurse should provide the client with which information about this medication?

"Pain in the back of the leg should be reported."

The nurse is preparing a subcutaneous dose of bethanechol prescribed for a client with urinary retention. Before giving the dose, the nurse checks to see that which medication is available on the emergency cart for use if needed?

Atropine sulfate

Following kidney transplantation, cyclosporine is prescribed for a client. Which laboratory result would indicate an adverse effect from the use of this medication?

Blood urea nitrogen level of 25 mg/dL (8.8 mmol/L) rationale: Cyclosporine is an immunosuppressant. Nephrotoxicity can occur from the use of cyclosporine. Nephrotoxicity is evaluated by monitoring for elevated blood urea nitrogen and serum creatinine levels. The normal blood urea nitrogen level is 10 to 20 mg/dL (3.6 to 7.1 mmol/L). The normal creatinine level for a male is 0.6 to 1.2 mg/dL (53 to 106 mcmol/L) and for a female is 0.5 to 1.1 mg/dL (44 to 97 mcmol/L). Cyclosporine can lower complete blood cell count levels. A normal hemoglobin is 14 to 18 g/dL (140 to 180 mmol/L) for a male and 12 to 16 g/dL (120 to 160 mmol/L) for a female. A normal hemoglobin is not an adverse effect. Cyclosporine does affect the glucose level. The normal fasting glucose is 70 to 99 mg/dL (3.9-5.5 mmol/L).

The nurse, who is administering bethanechol chloride, is monitoring for cholinergic overdose associated with the medication. The nurse should check the client for which sign of overdose?

Bradycardia rationale: Cholinergic overdose of bethanechol chloride produces manifestations of excessive muscarinic stimulation such as salivation, sweating, involuntary urination and defecation, bradycardia, and severe hypotension. Remember that the sympathetic nervous system speeds the heart rate and the cholinergic (parasympathetic) nervous system slows the heart rate. Treatment includes supportive measures and the administration of atropine sulfate (anticholinergic) subcutaneously or intravenously.

A client is prescribed dutasteride. Which outcome indicates that the medication is effective?

Decreased obstruction to outflow of urine through the urethra

The nurse is providing discharge instructions to a client receiving trimethoprim-sulfamethoxazole. Which instruction should be included in the list?

Drink 8 to 10 glasses of water per day. rationale: Each dose of trimethoprim-sulfamethoxazole should be administered with a full glass of water, and the client should maintain a high fluid intake to avoid crystalluria. The medication is more soluble in alkaline urine. The client should not be instructed to taper or discontinue the dose. Clients should be advised to use sunscreen since the skin becomes sensitive to the sun. Some forms of trimethoprim-sulfamethoxazole cause urine to turn dark brown or red. This does not indicate the need to notify the PHCP.

The nurse is taking care of a client receiving oxybutynin. Which finding should the nurse expect to note if the client develops side or adverse effects of this medication?

Dry mouth

The nurse is reviewing the laboratory results for a client receiving tacrolimus. Which laboratory result would indicate to the nurse that the client is experiencing an adverse effect of the medication?

Fasting blood glucose of 200 mg/dL (11.1 mmol/L) rationale: A fasting blood glucose level of 200 mg/dL (11.1 mmol/L) is significantly elevated above the normal range of 70 to 99 mg/dL (3.9-5.5 mmol/L) and suggests an adverse effect. Recall that fasting blood glucose levels are sometimes based on primary health care provider preference. Other adverse effects include neurotoxicity evidenced by headache, tremor, and insomnia; gastrointestinal effects such as diarrhea, nausea, and vomiting; hypertension; and hyperkalemia. The remaining options identify normal reference levels. The normal potassium level is 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L). The normal platelet count is 150,000 to 400,000 mm3 (5 to 10 × 109/L).

A client with chronic kidney disease is receiving epoetin alfa. Which laboratory result would indicate a therapeutic effect of the medication?

Hematocrit of 33% (0.33)

The ambulatory care nurse is providing instructions to a client with a urinary tract infection (UTI) being started on nitrofurantoin. The nurse should provide the client with which information?

If taken with meals, it will help decrease the risk for gastrointestinal (GI) upset.

A client with a urinary tract infection is receiving ciprofloxacin by the intravenous (IV) route. The nurse appropriately administers the medication by performing which action?

Infusing slowly over 60 minutes rationale: Ciprofloxacin is prescribed for treatment of mild, moderate, severe, and complicated infections of the urinary tract, lower respiratory tract, and skin and skin structure. A single dose is administered slowly over 60 minutes to minimize discomfort and vein irritation. Ciprofloxacin is not light-sensitive, may be infused through a peripheral IV access, and is not given by IV push method.

A client with chronic kidney disease (CKD) who is receiving an antihypertensive medication is experiencing frequent hypotensive episodes. The nurse reviews the client's medication record, knowing that which medication would have the greatest tendency to cause hypotension?

Methyldopa

Ciprofloxacin is prescribed for a client with a Pseudomonas aeruginosa infection of the urinary tract. The health care provider (HCP) should be questioned by the nurse about the prescription if which underlying condition is noted in the client's record?

Myasthenia gravis

A client is receiving oxybutynin. The nurse should suspect that this medication is prescribed to relieve which condition?

Overactive bladder

Oxybutynin chloride is prescribed for a client with urge incontinence. Which sign would indicate a possible toxic effect related to this medication?

Restlessness rationale: Toxicity (overdosage) of oxybutynin produces central nervous system excitation, such as nervousness, restlessness, hallucinations, and irritability. Other signs of toxicity include hypotension or hypertension, confusion, tachycardia, flushed or red face, and signs of respiratory depression. Drowsiness is a frequent side effect of the medication but does not indicate overdosage.

Trimethoprim-sulfamethoxazole is prescribed for a client. The nurse should instruct the client to report which symptom if it develops during the course of this medication therapy?

Sore throat rationale: Clients taking trimethoprim-sulfamethoxazole should be informed about early signs and symptoms of blood disorders that can occur from this medication. These include sore throat, fever, and pallor, and the client should be instructed to notify the primary health care provider (PHCP) if these occur. The other options do not require PHCP notification.

Parenteral bethanechol chloride is prescribed for a client with urinary retention. The nurse should plan to administer this medication by which route?

Subcutaneously

Tacrolimus is prescribed for a client who underwent a kidney transplant. Which instruction should the nurse include when teaching the client about this medication?

Take the oral medication every 12 hours at the same times every day. rationale: Tacrolimus is a potent immunosuppressant used to prevent organ rejection in transplant clients. It is important that the medication be taken at 12-hour intervals to maintain a stable blood level to prevent organ rejection. Adverse effects include hyperglycemia and hypertension, so the client does not eat frequently to avoid hypoglycemia or use precautions to avoid orthostatic hypotension. Tacrolimus is metabolized through the cytochrome P450 system, so grapefruit juice is not allowed. *Focus on the subject, teaching a transplant client regarding tacrolimus. Focus on the goal of avoiding organ rejection by maintaining a stable level of tacrolimus in the blood by taking the medication at regular intervals every day.

A client taking metronidazole telephones the home health nurse to report dark discoloration to the urine. The nurse interprets that the client's complaint warrants which nursing action at this time?

Tell the client that this is a harmless medication side effect.

Nitrofurantoin is prescribed for a client with a urinary tract infection. The client contacts the nurse and reports a cough, chills, fever, and difficulty breathing. The nurse should make which interpretation about the client's complaints?

The client is experiencing a pulmonary reaction requiring cessation of the medication. rationale: Nitrofurantoin can induce 2 kinds of pulmonary reactions: acute and subacute. Acute reactions, which are most common, manifest with dyspnea, chest pain, chills, fever, cough, and alveolar infiltrates. These symptoms resolve 2 to 4 days after discontinuing the medication. Acute pulmonary responses are thought to be hypersensitivity reactions. Subacute reactions are rare and occur during prolonged treatment. Symptoms (e.g., dyspnea, cough, malaise) usually regress over weeks to months following nitrofurantoin withdrawal. However, in some clients, permanent lung damage may occur. The remaining options are incorrect interpretations.

Phenazopyridine is prescribed for a client with a urinary tract infection. The nurse evaluates that the medication is effective based on which observation?

Urination is not painful. Phenazopyridine is a urinary analgesic. It is effective when it eliminates pain and burning with urination. It does not eliminate the bacteria causing the infection, so it would not make the urine clear amber. It does not treat urge incontinence. It will cause the client to have reddish-orange discoloration of urine, but this is a side effect of the medication, not the desired effect.

Nitrofurantoin is prescribed for a client with urinary tract infection. The nurse is instructing the client regarding the administration of the medication. Which information about the best time to take this medication should be included in the client's education?

With meals
