1. How is the stomach protected from damage by gastric acid?

• A. enzymes present in the stomach
• B. a protective bacteria in the stomach
• C. bicarbonate present in the stomach
• D. the mucus lining of the stomach

Correct answer: D

Rationale: The correct answer is D. The stomach is protected from gastric acid by a thick mucus lining that acts as a physical barrier, preventing the acid from eroding the stomach walls. Enzymes in the stomach help with digestion but do not play a significant role in protecting the stomach from acid damage, so choice A is incorrect. While some bacteria in the stomach can be beneficial, they do not primarily protect the stomach from gastric acid, making choice B incorrect. Bicarbonate, a base, can neutralize acid, but it is not the primary defense mechanism against gastric acid in the stomach, so choice C is also incorrect.

2. A healthcare professional is reviewing the lab results of a client who has bulimia nervosa. The professional should notify the provider of which of the following results?

• A. White Blood Cells 5,200/mm³
• B. Hemoglobin 14 g/dL
• C. Magnesium 1.6 mg/dL
• D. Potassium 3.2 mEq/L

Correct answer: D

Rationale: A potassium level of 3.2 mEq/L is below normal and requires provider notification, especially in clients with bulimia nervosa who are at risk of electrolyte imbalances. Low potassium levels can lead to serious complications like cardiac arrhythmias. The other options are within or close to the normal range and would not be a priority for notification.

3. Which of the following amino acids are considered indispensable?

• A. Lysine
• B. Methionine
• C. Tryptophan
• D. Valine

Correct answer: A

Rationale: The correct answer is A: Lysine. Indispensable amino acids are those that the body cannot synthesize and must be obtained from the diet. Lysine, methionine, and tryptophan are all examples of indispensable amino acids. However, the question specifically asked for 3 out of the 9 indispensable amino acids, making 'Lysine' the correct choice. Choices B, C, and D are also indispensable amino acids but are not the focus of the question.

4. A nurse is caring for four clients. The nurse should plan to administer total parenteral nutrition for which of the following clients?

• A. A client who is postoperative following a laminectomy and is receiving IV PCA
• B. A client who has dysphagia and does not recognize his family
• C. A client who has COPD and is going home with oxygen
• D. A client who has colon cancer and will undergo a hemicolectomy

Correct answer: D

Rationale: Total parenteral nutrition (TPN) is essential for clients undergoing significant surgical procedures like a hemicolectomy to ensure they receive adequate nutrition when oral intake is not possible. Choices A, B, and C do not typically require TPN. Choice A is managing postoperative pain with IV PCA, choice B is likely to need alternative feeding methods due to dysphagia, and choice C is going home with oxygen for COPD management, which does not directly relate to the need for TPN.

5. You are to apply a transdermal patch of nitoglycerin to your client. The following are important guidelines to observe EXCEPT:

• A. Apply to hairless clean area of the skin not subject to much wrinkling
• B. Patches may be applied to distal part of the extremities like forearm
• C. Change application and site regularly to prevent irritation of the skin
• D. Wear gloves to avoid any medication on your hand

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
