Which treatment is likely to be planned for a patient who develops pernicious anemia after a gastrectomy?
Triple-drug therapy.
IV therapy.
Quadruple-drug therapy.
Cobalamin replacement therapy.
The Correct Answer is D
Choice A rationale:
Triple-drug therapy is not the standard treatment for pernicious anemia after a gastrectomy. Pernicious anemia is primarily caused by vitamin B12 deficiency due to the absence of intrinsic factor, which is essential for vitamin B12 absorption.
Choice B rationale:
IV therapy is a broad term and does not specify the treatment for pernicious anemia. In the context of pernicious anemia, cobalamin replacement therapy administered via intramuscular injections is the preferred treatment.
Choice C rationale:
Quadruple-drug therapy is not a recognized treatment for pernicious anemia. The primary treatment for pernicious anemia involves cobalamin replacement therapy to address the vitamin B12 deficiency.
Choice D rationale:
Cobalamin replacement therapy is the appropriate treatment for pernicious anemia after a gastrectomy. Since the patient lacks intrinsic factor, which is necessary for vitamin B12 absorption, cobalamin replacement therapy bypasses the need for intrinsic factor and provides the necessary vitamin B12 directly.

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.
Correct Answer is B
Explanation
Choice A rationale:
Dizziness with a blood pressure of 150/92 mm Hg indicates hypertension, but it is not an immediate life-threatening condition requiring urgent assessment compared to a severe headache and vomiting.
Choice B rationale:
A severe headache and vomiting could be indicative of a serious neurological condition such as a stroke, intracranial bleeding, or increased intracranial pressure. This patient needs urgent assessment and intervention to prevent potential complications.
Choice C rationale:
A hip fracture with a pain level of 2 on a 1-to-10 scale suggests pain but is not immediately life-threatening compared to symptoms like severe headache and vomiting.
Choice D rationale:
Fatigue after receiving an ACE inhibitor is a common side effect and, while important to monitor, does not pose an immediate threat compared to the symptoms of severe headache and vomiting.
