💉The prescription specifically requires 10 units of regular insulin, which is a rapid-acting preparation used for glucose correction.

🧪A 70/30 insulin mixture contains 70% isophane insulin and only 30% regular insulin.

⚠️The nurse cannot accurately separate regular insulin from the premixed vial because both insulin types are already combined in solution.

✅Obtaining regular insulin and withdrawing exactly 10 units ensures accurate medication administration.

📌Core Message:

A prescription for regular insulin must be prepared from a vial of regular insulin alone, because a premixed 70/30 formulation cannot be separated into its individual components.

🧠A worsening headache during vasopressin therapy can indicate water intoxication and dilutional hyponatremia.

💧Vasopressin promotes renal water reabsorption, which can produce excessive fluid retention if the dose is too high.

🚨Progressive hyponatremia can cause headache, confusion, drowsiness, seizures, and other signs of cerebral edema.

📞The nurse should promptly report the headache and assess the client’s neurologic status, fluid balance, weight, and serum sodium level.

📌Core Message:

A worsening headache during vasopressin therapy may indicate water intoxication and hyponatremia, requiring prompt evaluation and provider notification.

💥Severe pain rated 8 requires follow-up because uncontrolled rib-fracture pain limits deep breathing and effective coughing.

🫁A respiratory rate of 28 breaths/minute indicates tachypnea, which may result from pain or developing respiratory compromise.

🌬️Shallow breathing reduces alveolar ventilation and increases the risk of atelectasis, retained secretions, and pneumonia.

🩺These findings require prompt pain management and continued assessment of breath sounds, oxygenation, and respiratory effort.

📌Core Message:

Severe pain, tachypnea, and shallow respirations require follow-up because they increase the client’s risk for hypoventilation and pulmonary complications.

💊The client has severe rib-fracture pain that has not responded adequately to acetaminophen.

🫁Effective analgesia enables deeper breathing, coughing, repositioning, and participation in pulmonary hygiene.

💉An opioid analgesic can provide appropriate relief for acute severe traumatic pain.

👀The nurse must monitor respiratory rate, sedation, oxygen saturation, and pain response because opioids can cause respiratory depression.

📌Core Message:

Opioid analgesics are appropriate for severe rib-fracture pain because effective pain control supports ventilation and prevents pulmonary complications.

🫁Morphine suppresses the brainstem’s respiratory center and may cause respiratory depression.

📊Obtaining the respiratory rate provides essential baseline respiratory data before opioid administration.

⚠️This client already has shallow breathing from rib-fracture pain, increasing the importance of assessing respiratory depth and effort.

🛑The nurse should withhold morphine and notify the healthcare provider if clinically significant respiratory depression is present.

📌Core Message:

Respiratory rate, depth, and effort must be assessed before administering morphine because opioids can suppress ventilation.

🚑Naloxone reverses opioid-induced respiratory and central nervous system depression.

🚽Docusate sodium helps prevent or manage constipation caused by reduced gastrointestinal motility during opioid therapy.

🤢Ondansetron treats nausea and vomiting, which are common opioid adverse effects.

🩺These medications address potentially serious or uncomfortable morphine-related adverse effects without adding another opioid.

📌Core Message:

Naloxone, docusate sodium, and ondansetron manage important morphine adverse effects, including respiratory depression, constipation, nausea, and vomiting.

💓Rest decreases myocardial workload and reduces the heart’s oxygen demand during an anginal episode.

💊Nitroglycerin dilates coronary and systemic blood vessels, improving myocardial oxygen supply while reducing cardiac workload.

🪑The client should remain seated or lying down because nitroglycerin can cause hypotension and dizziness.

⏱️The nurse should reassess chest pain and vital signs approximately 5 minutes after the dose and follow the prescribed nitroglycerin protocol.

📌Core Message:

Rest after nitroglycerin administration reduces cardiac workload and oxygen demand while limiting injury from dizziness or hypotension.

🧠Haloperidol strongly blocks dopamine receptors and can produce extrapyramidal symptoms.

🏃Akathisia is characterized by severe inner restlessness, pacing, repetitive movements, and an inability to remain still.

🔍The nurse should distinguish akathisia from anxiety or agitation because it requires specific medication management.

💊Treatment may involve reducing the antipsychotic dose or administering a prescribed beta blocker, benzodiazepine, or anticholinergic medication.

📌Core Message:

Akathisia is a haloperidol-related extrapyramidal effect manifested by restlessness, pacing, and inability to remain still.

🦋Propylthiouracil inhibits new thyroid-hormone synthesis and reduces peripheral conversion of T4 to T3.

⏰Propylthiouracil must be administered before Lugol’s solution so the thyroid cannot use the administered iodine to produce additional thyroid hormone.

🧪Lugol’s solution is given afterward to inhibit thyroid-hormone release and reduce thyroid gland vascularity.

🚨Giving iodine before the antithyroid medication can provide substrate for new hormone production and worsen hyperthyroidism.

📌Core Message:

Propylthiouracil should precede Lugol’s solution by at least one hour to prevent iodine from being used for new thyroid-hormone synthesis.

🛡️Sucralfate forms a protective barrier over the ulcerated gastrointestinal mucosa.

🍽️It should be administered on an empty stomach, usually 1 hour before meals and at bedtime.

⏰Food can interfere with sucralfate’s ability to bind effectively to the ulcer site.

💊Other medications should generally be separated from sucralfate because it can reduce their gastrointestinal absorption.

📌Core Message:

Sucralfate should be taken on an empty stomach before meals so it can bind to the ulcer and form a protective barrier.
