The healthcare provider prescribes enoxaparin sodium 80 mg subcutaneously twice daily. The nurse is preparing a preloaded 1 mL syringe labeled, 'enoxaparin sodium injection, USP 60 mg/0.6 mL'. How many mL should the nurse administer?

(Enter numeric value only. If rounding is required, round to the nearest tenth.)

Choice A reason:

Taking an initial respiratory rate is a necessary action to ensure safety during morphine administration, as morphine can cause respiratory depression, which is a potentially life-threatening side effect. The nurse should monitor the client's respiratory rate and oxygen saturation regularly and report any signs of respiratory distress or hypoxia to the physician. Therefore, choice A is correct.

Choice B reason:

Performing a 12-lead electrocardiogram is not a necessary action to ensure safety during morphine administration, as morphine does not have a significant effect on the cardiac rhythm or conduction. The nurse should monitor the client's heart rate and blood pressure regularly and report any signs of bradycardia, hypotension, or chest pain to the physician. Therefore, choice B is incorrect.

Choice C reason:

Suctioning the client to clear the airway is not a necessary action to ensure safety during morphine administration, as morphine does not cause excessive secretions or bronchospasm that would obstruct the airway. The nurse should assess the client's level of consciousness and gag reflex regularly and report any signs of sedation, confusion, or aspiration to the physician. Therefore, choice C is incorrect.

Choice D reason:

Having a manual resuscitation bag at the bedside is a necessary action to ensure safety during morphine administration, as morphine can cause respiratory depression that may require emergency intervention. The nurse should be prepared to administer oxygen and naloxone (an opioid antagonist) as ordered and perform rescue breathing or cardiopulmonary resuscitation if needed. Therefore, choice D is correct.

Choice E reason:

Asking the client about other medications she takes is a necessary action to ensure safety during morphine administration, as morphine can interact with other drugs that may enhance or reduce its effects or cause adverse reactions. The nurse should review the client's medication history and current medications and report any potential drug interactions or contraindications to the physician. Therefore, choice E is correct.

Choice F reason:

Restraining the client with soft restraints is not a necessary action to ensure safety during morphine administration, as morphine does not cause agitation or delirium that would warrant physical restraint. The nurse should provide a safe and comfortable environment for the client and report any signs of anxiety, hallucinations, or psychosis to the physician. Therefore, choice F is incorrect.

Choice A reason: Expectorating bronchial secretions is not an assessment information that indicates that the antitussive medication benzonatate is effective. Benzonatate is a medication that suppresses the cough reflex by numbing the throat and lungs. It does not loosen or thin the mucus in the airways, which would facilitate expectoration.

Choice B reason: Reports reduced nasal discharge is not an assessment information that indicates that the antitussive medication benzonatate is effective. Benzonatate is a medication that suppresses the cough reflex by numbing the throat and lungs. It does not affect the production or drainage of nasal secretions, which are caused by inflammation and infection in the upper respiratory tract.

Choice C reason: Able to sleep through the night is not an assessment information that indicates that the antitussive medication benzonatate is effective. Benzonatate is a medication that suppresses the cough reflex by numbing the throat and lungs. It does not have any sedative or hypnotic effects, which would promote sleep. However, by reducing coughing, benzonatate may indirectly improve the quality of sleep for the client.

Choice D reason: Denies having coughing spells is an assessment information that indicates that the antitussive medication benzonatate is effective. Benzonatate is a medication that suppresses the cough reflex by numbing the throat and lungs. It reduces the frequency and intensity of coughing, which can relieve discomfort and irritation for the client.
