The nurse is teaching a primigravida about preeclampsia. What finding(s) are indicators of preeclampsia and should be reported to the healthcare provider? Select all that apply.

A. Humidifier bottle

Rationale: A humidifier bottle is often used with oxygen therapy to add moisture to the oxygen, preventing dryness of the nasal passages and throat. It is important for patient comfort, especially when oxygen is administered at higher flow rates for prolonged periods.

B. Lamb's wool

Rationale: Lamb's wool is not needed for starting oxygen therapy. It is typically used to provide padding and comfort in other situations, such as preventing pressure sores, but it has no role in the administration of oxygen.

C. Flowmeter

Rationale: A flowmeter is necessary to regulate the flow rate of oxygen. It ensures that the client receives the prescribed amount of oxygen (3 L/minute in this case), making it an essential component for administering oxygen therapy.

D. Tape

Rationale: Tape is not required for administering oxygen via a nasal cannula. It might be used to secure tubing in other contexts, but it is not specifically needed for starting oxygen therapy. The nasal cannula usually stays in place without the need for tape.

E. Suction cannister

Rationale: A suction canister is used in suctioning procedures to collect secretions and is not needed for starting oxygen therapy. It is relevant for managing airway secretions but unrelated to the administration of oxygen.

F. Nasal cannula

Rationale: A nasal cannula is the device through which oxygen is delivered to the client. It is specifically mentioned in the order and is essential for administering the oxygen.

G. Sterile water

Rationale: Sterile water is used to fill the humidifier bottle to provide humidified oxygen. This helps to prevent the drying effects of oxygen therapy on the mucous membranes, enhancing patient comfort.

Step-by-step Calculation:

1. We need to find the volume (in mL) of teriparatide that contains the desired dose of 60 mcg.
2. Set up the proportion:

dose (mcg) / concentration (mcg/mL) = volume (mL)

1. Fill in the known values:
   • Dose (mcg): 60 mcg (as given in the problem)
   • Concentration (mcg/mL): 750 mcg/2.4 mL (from the medication label)
2. Solve for the volume:
   • Multiply both sides of the proportion by the concentration to isolate the volume on the left:
   • dose (mcg) = volume (mL) concentration (mcg/mL)
   • Substitute the known values:
   • 60 mcg = volume (mL) (750 mcg / 2.4 mL)
3. Calculate the volume:
   • Divide both sides by the concentration to solve for the volume:
   • volume (mL) = 60 mcg / (750 mcg / 2.4 mL)
   • Simplify:
   • volume (mL) = (60 mcg 2.4 mL) / 750 mcg
   • volume (mL) = 0.192 mL (approximately)
4. Rounding (optional): The problem specifies rounding to the nearest tenth. Since 0.192 is closer to 0.2 than 0.1, the rounded volume is:
5. volume (mL) = 0.2 mL (rounded to one decimal place)

Therefore, the nurse should administer 0.2 mL of teriparatide.
