Question

A client is receiving amphotericin B intravenous for treatment of a fungal infection. Which laboratory result is most important for the nurse to report to the healthcare provider (HCP)?

Reference Range

Creatinine [0.5 to 1.1 mg/dL (44 to 97 µmol/L)]

Hematocrit (Hct) [42% to 52% (0.42 to 0.52 volume fraction)]

Potassium (K+) [3.5 to 5 mEq/L (3.5 to 5 mmol/L)]

Platelets [150,000 to 400000 / m * m ^ 3 (150 to 400 * 10 ^ 9 / L )]

Answer 1

Correct Answers:

Creatinine 3.8 mg/dL (336 µmol/L)

Rationale :

🧪 A creatinine level of 3.8 mg/dL is markedly elevated and strongly suggests significant renal impairment.

🧪 Amphotericin B is well known for causing dose-related nephrotoxicity, making renal function one of the most important parameters to monitor.

🧪 Kidney injury can also lead to electrolyte disturbances, particularly hypokalemia and hypomagnesemia, which can produce additional complications.

🧪 A major increase in creatinine may require adjustment, interruption, or reconsideration of amphotericin B therapy depending on the clinical situation.

🧪 The nurse should therefore report this result promptly to the healthcare provider to prevent progression of potentially serious renal damage.

Answer 2

Correct Answers:

Be alert for possible cross-sensitivity to cephalosporin agents.

Rationale :

💊 A severe maculopapular rash after penicillin suggests a clinically important beta-lactam hypersensitivity reaction.

💊 Penicillins and cephalosporins share structural similarities, so some clients with penicillin allergy may also react to certain cephalosporins.

💊 The degree of cross-reactivity depends partly on the specific cephalosporin and similarity of its side chain to the penicillin involved.

💊 The client should inform all healthcare providers and pharmacists about the prior penicillin reaction before receiving another beta-lactam antibiotic.

💊 Teaching about possible cephalosporin cross-sensitivity is therefore the most relevant safety information for future antibiotic prescriptions.

Answer 3

Correct Answers:

Notify the healthcare provider of the finding.

Rationale :

🦴 A total calcium level of 5.5 mg/dL represents severe hypocalcemia compared with the stated normal range of 9 to 10.4 mg/dL.

🦴 Severe hypocalcemia can cause tetany, muscle spasms, seizures, laryngospasm, and potentially dangerous cardiac dysrhythmias.

🦴 Corticosteroids such as methylprednisolone can further impair calcium balance by reducing intestinal calcium absorption and increasing bone loss with continued therapy.

🦴 The healthcare provider should be notified promptly so the cause can be evaluated and appropriate calcium replacement or other treatment initiated.

🦴 Immediate clinical evaluation takes priority over dietary teaching or routine medication administration because this laboratory value represents a significant safety concern.

Answer 4

Correct Answers:

Advise the client to review medication use with the healthcare provider.

Rationale :

💊 The client is using acetaminophen, ibuprofen, and daily aspirin, creating important risks for medication interactions and adverse effects.

💊 Ibuprofen combined with aspirin increases the risk for gastrointestinal irritation, ulceration, and bleeding, particularly in an older adult.

💊 NSAID use can also impair renal function and may interfere with the antiplatelet effect of low-dose aspirin depending on timing.

💊 Frequent acetaminophen use adds concern for excessive total daily dosing and possible hepatotoxicity, especially if other acetaminophen-containing products are used.

💊 The safest priority is for the client to review the entire pain-management regimen with the healthcare provider before continuing frequent combined use.

Answer 5

Correct Answers:

"I'll take my usual oral contraceptives for birth control."

Rationale :

🟠 Rifampin is a potent hepatic enzyme inducer that can increase the metabolism of estrogen and progestin components in oral contraceptives.

🟠 This interaction can substantially reduce contraceptive effectiveness and increase the risk for unintended pregnancy.

🟠 Clients should be instructed to use an alternative or additional nonhormonal contraceptive method while taking rifampin and for the recommended period afterward.

🟠 The client should discuss the most appropriate contraceptive strategy with the healthcare provider before relying on oral contraceptives alone.

🟠 This statement therefore indicates a need for further teaching.

Answer 6

Correct Answers:

Take additional doses as needed.

Rationale :

💊 Acetaminophen should be taken only at the prescribed or labeled dose and at the recommended dosing interval.

💊 Taking additional doses can cause unintentional overdose and severe hepatotoxicity, particularly when multiple products containing acetaminophen are used.

💊 Clients should carefully check combination cold, flu, and pain medications because many contain acetaminophen.

💊 Excessive intake can lead to acute liver failure, which may initially produce few symptoms before significant injury becomes apparent.

💊 This statement requires additional teaching because the client should never take extra doses beyond the recommended total daily amount.

Answer 7

Correct Answers:

Contact the healthcare provider (HCP).

Rationale :

🚨 The client has a history of anaphylactic reaction to penicillin, which represents a severe immediate hypersensitivity reaction.

🚨 Cephalexin is a first-generation cephalosporin and may have clinically relevant cross-reactivity with certain penicillins because of structural similarities.

🚨 Administering the medication without clarification could expose the client to another potentially life-threatening reaction, including anaphylaxis.

🚨 The nurse should withhold the dose and contact the healthcare provider to verify whether an alternative antibiotic should be prescribed.

🚨 Prevention of a repeat severe allergic reaction takes priority over routine medication administration.

Answer 8

Correct Answers:

Severe itching.

Rationale :

🌿 Severe itching can be an early manifestation of a hypersensitivity reaction to diclofenac.

🌿 Pruritus may precede visible urticaria, facial swelling, bronchospasm, or more severe systemic allergic manifestations.

🌿 Recognizing the reaction early allows the medication to be stopped and the client assessed before symptoms progress.

🌿 Clients with NSAID hypersensitivity can develop serious reactions, including angioedema and anaphylaxis.

🌿 Severe itching is therefore the earliest finding among the choices suggesting a possible allergic response.

Answer 9

Correct Answers:

Check stool for occult blood.

Rationale :

🩸 Aspirin inhibits cyclooxygenase and platelet aggregation, increasing the client's risk for gastrointestinal mucosal injury and bleeding.

🩸 A dosage of 650 mg four times daily represents substantial ongoing aspirin exposure, making gastrointestinal complications particularly important to monitor.

🩸 Occult blood testing can detect gastrointestinal bleeding before the client develops obvious melena or hematemesis.

🩸 Continued blood loss can lead to anemia, hypovolemia, and more serious complications if it is not recognized early.

🩸 Checking stool for occult blood is therefore the most important intervention among the available choices.

Answer 10

Correct Answers:

Instruct the client to take the morphine sulfate every 12 hours as prescribed.

Rationale :

💊 Morphine prescribed every 12 hours for chronic pain is intended to maintain a relatively consistent analgesic effect and prevent severe breakthrough pain.

💊 Waiting until the pain becomes intense can make pain more difficult to control and may lead to unnecessary fluctuations in comfort and function.

💊 Scheduled dosing maintains steadier opioid concentrations and supports more consistent participation in sleep, mobility, and daily activities.

💊 The nurse should reinforce adherence while also teaching the client about adverse effects such as sedation, constipation, and respiratory depression.

💊 Taking the medication every 12 hours as prescribed is therefore the most appropriate action for effective chronic pain management.
