An infant who weighs 22 lbs. receives a prescription for amoxicillin 20 mg/kg/day PO in divided doses every 8 hours. The bottle is labeled, "Amoxicillin for Oral Suspension, USP 250 mg per 5 mL." How many mL should the nurse administer with each dose? (Enter numerical value only. If rounding is necessary, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["1.3"]

Convert the infant's weight from pounds (lb) to kilograms (kg).

Given weight = 22 lb

Conversion factor = 1 kg = 2.2 lb

Weight (kg) = (Weight in lb / 2.2 lb/kg)

= (22 / 2.2)

= 10 kg.

Calculate the total daily dose in milligrams (mg/day).

Prescribed dose = 20 mg/kg/day

Total Daily Dose (mg/day) = Weight (kg) x Dose (mg/kg/day)

= 10 kg x 20 mg/kg/day = 200 mg/day.

Calculate the single dose in milligrams (mg/dose).

Frequency = every 8 hours (3 doses per day)

Single Dose (mg/dose) = (Total Daily Dose / Number of doses per day)

= (200 mg / 3)

= 66.67 mg.

Calculate the volume in milliliters (mL) to administer per dose.

Available concentration = 250 mg per 5 mL

Volume (mL/dose) = (Single Dose (mg) / Available concentration (mg)) x Available volume (mL)

= (66.67 mg / 250 mg) x 5 mL

= 1.333... mL.

Round the answer to the nearest tenth.

= 1.3 mL.

Correct Answer is A

Explanation

A. Palpate the client's suprapubic area for distention: Palpating for bladder distention helps determine if urinary retention is present, which is common in older men with possible benign prostatic hyperplasia (BPH). Assessing retention is a priority because unresolved urinary obstruction can lead to hydronephrosis or kidney damage.

B. Instruct in effective techniques to cleanse the glans penis: Proper hygiene is important for preventing infection, especially in uncircumcised males, but it does not address the client’s primary problem of urinary retention and obstructive symptoms.

C. Obtain a urine specimen for culture and sensitivity: While urinary tract infections can occur in clients with urinary retention, the presenting symptoms here are more indicative of obstruction due to prostate enlargement. A culture may be ordered later, but not the first step.

D. Advise the client to maintain a voiding diary for one week: A voiding diary provides helpful long-term information about urinary patterns, but it does not address the acute issue of a bladder that may be distended and retaining urine.

A. St. John's wort B. Sildenafil C. Ondansetron D. Naloxone

Correct Answer is ["C","D","F"]

Explanation

A. St. John's wort: This herbal supplement is not used to manage opioid side effects and may interact with other medications, including opioids, making it inappropriate for this purpose.

B. Sildenafil: Sildenafil is used to treat erectile dysfunction and has no role in managing morphine side effects. It is unrelated to pain management or opioid-related adverse effects.

C. Ondansetron: Ondansetron is an antiemetic commonly prescribed to prevent or treat nausea and vomiting, which are frequent side effects of morphine administration.

D. Naloxone: Naloxone is an opioid antagonist used to reverse severe opioid-induced respiratory depression. It is essential for emergency management of potentially life-threatening side effects of morphine.

E. Meperidine: Meperidine is an opioid analgesic and is not used to treat side effects of morphine. Using another opioid would not address morphine-induced complications and may increase risk of adverse effects.

F. Docusate sodium: Opioid-induced constipation is common with morphine. Docusate sodium is a stool softener used prophylactically to prevent or treat constipation associated with opioid therapy.
