Which fluid replacement therapy would the nurse prepare to administer for a patient who is exhibiting clinical manifestations of hypovolemic shock?
0.459% saline.
0.9% NaCl.
5% dextrose in 0.45% saline.
Dextran.
The Correct Answer is B
Choice A rationale:
0.459% saline is a hypotonic solution with a lower concentration of salt than the normal physiological range (0.9% NaCl) Hypotonic solutions can cause red blood cells to swell and potentially burst due to the osmotic imbalance, making it inappropriate for hypovolemic shock.
Choice B rationale:
0.9% NaCl, also known as normal saline, is an isotonic solution with a salt concentration similar to the body's own fluids. Isotonic solutions are ideal for hypovolemic shock as they help to expand the intravascular volume without causing significant shifts of fluid and electrolytes within the body compartments.
Choice C rationale:
5% dextrose in 0.45% saline is a hypotonic solution with a low salt concentration. While it provides some fluid replacement, it doesn't address the electrolyte imbalance adequately, which is crucial in hypovolemic shock.
Choice D rationale:
Dextran is a plasma volume expander but is not the first-line choice for hypovolemic shock. It might be used in certain situations, but isotonic crystalloids like 0.9% NaCl are preferred for rapid volume expansion and stabilization of the patient.

Correct Answer is C
Explanation
The correct answer is choice c. “I will take my iron supplement along with meals.”
Choice A rationale:
Taking iron supplements with a straw is recommended to prevent staining of the teeth, which is a common side effect of liquid iron supplements.
Choice B rationale:
Taking iron supplements at bedtime can be beneficial for some patients, especially if they experience gastrointestinal discomfort when taking iron during the day.
Choice C rationale:
Taking iron supplements with meals can decrease the absorption of iron. Iron is best absorbed on an empty stomach, although it can be taken with food if gastrointestinal upset occurs.
Choice D rationale:
Taking iron supplements with orange juice is recommended because vitamin C enhances the absorption of iron.
Correct Answer is C
Explanation
The correct answer is choice C. Uses an alcohol-based mouthwash twice a day.
Choice A rationale:
Drinking 14 glasses of water daily is generally beneficial as it helps maintain hydration and supports overall health. However, it is important to balance fluid intake to avoid overhydration.
Choice B rationale:
Shaving with an electric razor is recommended for patients with thrombocytopenia because it reduces the risk of cuts and bleeding compared to using a traditional razor.
Choice C rationale:
Using an alcohol-based mouthwash can cause dryness and irritation of the oral mucosa, which can lead to bleeding, especially in patients with thrombocytopenia. It is better to use a non-alcoholic mouthwash.
Choice D rationale:
Brushing teeth with a soft-bristle toothbrush is advised to minimize the risk of gum bleeding and maintain oral hygiene.
