The healthcare provider prescribes bismuth subsalicylate, metronidazole, tetracycline, and pantoprazole for a client with a Helicobacter pylori (H. pylori) infection.
Prior to administering the
H. pylori treatment regimen, the nurse should review the electronic medical record for which medication?

Choice A rationale:

Autoimmune responses occur when the immune system mistakenly attacks the body's own tissues. They are not typically triggered by allergens like bee stings.

Autoimmune responses often develop slowly over time and present with symptoms related to the specific tissues being attacked.

The rapid onset of symptoms in this case, along with the specific symptoms of rash, shortness of breath, and low blood pressure, are not characteristic of an autoimmune response.

Choice B rationale:

Type II hypersensitivity reactions involve antibodies that target and destroy cells or tissues. These reactions often take hours or days to develop, rather than minutes.

Examples of type II hypersensitivity reactions include transfusion reactions, hemolytic disease of the newborn, and some autoimmune diseases.

The rapid onset of symptoms in this case is not consistent with a type II hypersensitivity reaction.

Choice C rationale:

Cell-mediated hypersensitivity reactions involve T cells that directly attack cells or tissues. These reactions typically take 1-3 days to develop.

Examples of cell-mediated hypersensitivity reactions include contact dermatitis (e.g., poison ivy), graft-versus-host disease, and some drug reactions.

The rapid onset of symptoms in this case, as well as the specific symptoms of rash, shortness of breath, and low blood pressure, are not characteristic of a cell-mediated hypersensitivity reaction.

Choice D rationale:

IgE response hypersensitivity reactions are the most immediate type of allergic reaction.

They are mediated by immunoglobulin E (IgE) antibodies, which bind to mast cells and basophils.

When an allergen (like bee venom) cross-links IgE antibodies on mast cells, it triggers the release of histamine and other inflammatory mediators.

These mediators cause vasodilation, increased vascular permeability, smooth muscle contraction, and mucus secretion, leading to the characteristic symptoms of an allergic reaction.

The rapid onset of symptoms in this case, including rash, shortness of breath, and low blood pressure, are consistent with an IgE-mediated hypersensitivity reaction.

Choice A rationale:

While ABGs can provide valuable information about a patient's respiratory status, they are not routinely required prior to postural drainage in patients with COPD.

ABGs might be considered if the patient is experiencing acute respiratory distress or if there are concerns about their oxygenation or ventilation status.

However, in the absence of such concerns, obtaining ABGs would not be necessary and could potentially cause discomfort or anxiety for the patient.

Choice C rationale:

Performing postural drainage immediately after meals is not recommended for patients with COPD.

This is because eating can cause a feeling of fullness in the stomach, which can make it difficult for the patient to breathe deeply and effectively during the procedure.

Additionally, there is a risk of aspiration if the patient were to vomit during or after postural drainage.

It is generally recommended to perform postural drainage at least 1-2 hours after meals to reduce these risks.

Choice D rationale:

Instructing the patient to breathe shallow and fast is not appropriate for postural drainage.

The goal of postural drainage is to help the patient mobilize and expectorate secretions from the lungs.

This is best achieved by encouraging the patient to breathe deeply and slowly, which helps to open up the airways and promote mucus clearance.

Shallow, rapid breathing can actually make it more difficult to clear secretions and can lead to increased shortness of breath.

Choice B rationale:

Explaining that the patient may be placed in five positions is the most appropriate approach for postural drainage in a patient with COPD.

This is because different positions help to drain different areas of the lungs. The five positions typically used for postural drainage are:

Head down position (to drain the lower lobes)

Prone position (to drain the posterior segments of the lungs)

Right lateral position (to drain the right middle lobe and right lower lobe) Left lateral position (to drain the left lower lobe)

Sitting upright position (to drain the upper lobes)

By placing the patient in these different positions, the nurse can help to ensure that all areas of the lungs are drained effectively.
