A nurse is preparing to administer lactulose 30 g PO four times daily to a client who has portal-systemic encephalopathy. The amount available is lactulose al solution 10 g/15 ml. How many ml. should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero)
The Correct Answer is ["45"]
Identify the ordered dose and the available concentration
Ordered Dose: 30 g
Available Concentration: 10 g per 15 mL
Calculate the volume to administer per dose using the Dose/Have method
Amount to administer = (Ordered Dose ÷ Dose on Hand) × Quantity
Quantity corresponding to the Dose on Hand = 15 mL
Volume = (30 ÷ 10) × 15
= 3 × 15
= 45 mL

Correct Answer is D
Explanation
A. Decrease in blood pressure: Autonomic dysreflexia is characterized by a sudden increase in blood pressure, not a decrease. Hypotension is more typical of spinal shock, making low blood pressure inconsistent with autonomic dysreflexia.
B. Increase in heart rate: During autonomic dysreflexia, the body often responds with bradycardia rather than tachycardia due to baroreceptor-mediated parasympathetic activation. An elevated heart rate is not a typical sign of this condition.
C. Client report of eye twitching: Eye twitching is not associated with autonomic dysreflexia. This symptom may indicate a neurological or electrolyte issue, but it does not help identify the acute hypertensive crisis characteristic of autonomic dysreflexia.
D. Client report of sudden headache: A sudden, severe headache is a hallmark symptom of autonomic dysreflexia caused by abrupt hypertension. This finding, along with other signs such as flushed skin, nasal congestion, and sweating above the level of injury, indicates the need for immediate intervention to prevent complications such as stroke.
Correct Answer is D
Explanation
A. Compensation: Compensation involves emphasizing a strength to make up for a perceived weakness or deficiency. Preparing a deceased partner’s favorite meals does not serve to offset a personal deficiency, so this is not the correct defense mechanism.
B. Dissociation: Dissociation is the temporary detachment from reality or identity to cope with stress or trauma. Cooking familiar meals does not indicate a detachment from reality; the client is fully aware of their actions and circumstances.
C. Rationalization: Rationalization involves creating logical explanations to justify unacceptable behaviors or feelings. Cooking meals for a deceased partner is not an attempt to justify behavior but a coping mechanism, so rationalization does not apply.
D. Denial: Denial is a defense mechanism in which a person refuses to accept reality or facts to avoid emotional pain. Continuing to cook meals for a deceased partner reflects the client’s difficulty accepting the loss, making denial the most appropriate identification of their behavior.
