A nurse is caring for an adolescent client who has cystic fibrosis. Which of the following actions should the nurse instruct the client to take prior to initiating postural drainage?

Choice A reason:

Measuring the arm circumference above the insertion site daily is appropriate. When planning care for a client scheduled to receive a peripherally inserted central catheter (PICC) in the arm, it is appropriate for the nurse to include measuring the arm circumference above the insertion site daily. This intervention is essential to monitor for any signs of complications, such as edema or swelling, which could indicate thrombosis or infiltration at the insertion site.

Choice B reason:

Administering sedation Administering sedation is not a routine intervention for a PICC insertion procedure is inappropriate. Sedation might be considered for certain procedures, but it is not typically used for PICC insertions. PICC insertions are generally performed with local anaesthesia at the insertion site.

Choice C reason:

Scheduling an MRI post procedure to verify placement An MRI is not typically used to verify the placement of a PICC. The placement of a PICC is usually confirmed using X-ray or other imaging methods that can visualize the catheter's location within the central veins. Post-procedure verification of PICC placement is essential to ensure proper positioning and to prevent complications.

Choice D reason:

Using gauze to secure an arm board to the involved extremity Using gauze to secure an arm board to the involved extremity is not a common practice for securing a PICC. After a PICC insertion, a securement device specifically designed for PICCs is typically used to secure the catheter in place and prevent movement.

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.
