A nurse in an emergency department is caring for a client who has a closed head injury. Which of the following actions should the nurse take first?
Prepare the client for an MRl of the brain.
Administer mannitol IV bolus to the client.
Determine the client's Glasgow Coma Scale score.
D insert an indwelling urinary catheter for the client.
The Correct Answer is C
The correct answer is choice C. Determine the client’s Glasgow Coma Scale score. This is because the Glasgow Coma Scale (GCS) is a tool to assess the level of consciousness and neurological status of a client who has a closed head injury. The GCS score can help guide the priority of interventions and the need for further diagnostic tests.
Choice A is wrong because an MRI of the brain is not the first action to take for a client who has a closed head injury. An MRI may be indicated later to evaluate the extent of brain damage, but it is not an emergency procedure.
Choice B is wrong because mannitol IV bolus is a medication that reduces intracranial pressure (ICP) by drawing fluid out of the brain tissue. However, mannitol should not be administered before confirming the presence and degree of increased ICP, which can be done by measuring the GCS score and other vital signs.
Choice D is wrong because inserting an indwelling urinary catheter for the client is not the first action to take for a client who has a closed head injury. A urinary catheter may be needed to monitor fluid balance and renal function, but it is not an urgent intervention.

Correct Answer is A
Explanation
The correct answer is choice A. Deep tendon reflexes 2+. This indicates that the client is receiving the therapeutic effect of magnesium sulfate, which is to prevent seizures by reducing neuromuscular excitability.
Magnesium sulfate is a mineral that is given intravenously to women with preeclampsia, a condition of high blood pressure and protein in the urine during pregnancy, to reduce the risk of seizures or eclampsia. It can also prolong pregnancy for up to two days, allowing drugs that speed up the baby’s lung development to be administered.
Choice B is wrong because 1+ proteinuria via urine dipstick is not a therapeutic effect of magnesium sulfate, but a sign of preeclampsia.
Proteinuria indicates that the kidneys are not working properly and are leaking protein into the urine. Magnesium sulfate does not improve the outcomes for the baby and can cause side effects such as respiratory depression for the mother.
Choice C is wrong because pulse rate 100/min is not a therapeutic effect of magnesium sulfate, but a possible side effect.
Magnesium sulfate can cause vasodilation, which lowers blood pressure and increases heart rate. A normal pulse rate for an adult is between 60 and 100 beats per minute. A pulse rate higher than 100 beats per minute may indicate tachycardia, which can be caused by various factors such as anxiety, dehydration, fever, infection, or medication.
Choice D is wrong because urine output 20 mL/hr is not a therapeutic effect of magnesium sulfate, but a sign of kidney failure. A normal urine output for an adult is between 800 and 2000 mL per day, or about 30 to 80 mL per hour. A urine output lower than 30 mL per hour may indicate oliguria, which can be caused by various factors such as dehydration, blood loss, shock, or kidney damage. Magnesium sulfate can cause renal toxicity if given in high doses or for prolonged periods.
Correct Answer is B
Explanation
B) I can visit my nephew who has chickenpox 5 days after the sores have crusted.
This statement indicates an understanding of infection prevention because it demonstrates knowledge about the contagious period of chickenpox. Visiting someone with chickenpox after the sores have crusted is a safe practice, as the person is no longer contagious.
The other options represent misconceptions about infection prevention:
A) Taking antibiotics for a viral infection is not effective, as antibiotics are used to treat bacterial infections, not viruses.
C) This statement is identical to option B and is incorrect.
D) Cleaning a cat's litter box during pregnancy is generally not recommended due to the risk of toxoplasmosis, a parasitic infection that can be transmitted through cat feces. Pregnant individuals are advised to have someone else handle cat litter or to use gloves and wash their hands thoroughly if they must do it themselves.
