Nursing Elites

1. An older adult patient comes to the clinic complaining of not being able to do what he used to be able to. You know that normal changes associated with aging include:

• A. Improved blood flow
• B. Slowed metabolic rate
• C. Increased brain weight
• D. Improved nerve fiber conduction

Correct answer: B

Rationale: Normal changes associated with aging include a slowed metabolic rate and decreased brain weight. Option A, 'Improved blood flow,' is incorrect as aging is generally associated with reduced vascular health rather than improved blood flow. Option D, 'Improved nerve fiber conduction,' is incorrect as aging typically leads to a decline in nerve function rather than improvement.

2. A patient with a history of breast cancer is being prescribed tamoxifen (Nolvadex). The nurse should educate the patient about what potential side effect of this medication?

• A. Increased risk of venous thromboembolism
• B. Increased risk of hot flashes
• C. Increased risk of cataracts
• D. Increased risk of bone fractures

Correct answer: A

Rationale: The correct answer is A: Increased risk of venous thromboembolism. Tamoxifen is known to increase the risk of venous thromboembolism, a serious side effect. Patients should be educated about the signs and symptoms of blood clots such as swelling, redness, warmth, or pain in the affected limb. Choices B, C, and D are incorrect because tamoxifen is not associated with an increased risk of hot flashes, cataracts, or bone fractures.

3. Which of the following is an example of a Type 1 hypersensitivity reaction?

• A. Anaphylaxis
• B. Indigestion
• C. Beta cell destruction
• D. ABO transfusion reaction

Correct answer: A

Rationale: Anaphylaxis is a classic example of a Type 1 hypersensitivity reaction. In Type 1 hypersensitivity, allergens trigger an immediate immune response mediated by IgE antibodies, leading to the release of histamine and other mediators. This reaction can result in symptoms ranging from mild itching and hives to severe conditions like anaphylaxis, which is a life-threatening emergency. The other options, such as indigestion (choice B), beta cell destruction (choice C), and ABO transfusion reaction (choice D), are not classified as Type 1 hypersensitivity reactions. Indigestion is typically related to gastrointestinal disturbances, beta cell destruction is associated with autoimmune conditions like type 1 diabetes, and ABO transfusion reaction involves antibodies targeting incompatible blood groups, which is a different immune mechanism compared to Type 1 hypersensitivity.

4. Which of the following birthmarks usually fade or regress as the child gets older?

• A. Hemangiomas
• B. Congenital dermal melanocytosis (i.e., Mongolian spots)
• C. Macular stains
• D. Hemangiomas, congenital dermal melanocytosis (i.e., Mongolian spots), and macular stains

Correct answer: D

Rationale: The correct answer is Hemangiomas, congenital dermal melanocytosis (i.e., Mongolian spots), and macular stains. These three types of birthmarks are known to fade or regress as the child gets older. Hemangiomas are vascular birthmarks that often shrink and disappear over time. Congenital dermal melanocytosis, commonly known as Mongolian spots, usually fade by adolescence. Macular stains, also called salmon patches, tend to lighten and fade as a child grows. The other choices are incorrect because they do not typically fade or regress with age.

5. When reviewing the purpose/action of neurotransmitters as they interact with different receptors, the nursing instructor gives an example using acetylcholine. When acetylcholine is released at the sinoatrial node in the right atrium of the heart, it is:

• A. positively charged.
• B. inhibitory.
• C. overstimulated.
• D. dormant.

Correct answer: B

Rationale: Acetylcholine acts as an inhibitory neurotransmitter at the sinoatrial node. It slows down the heart rate by decreasing the firing rate of the sinoatrial node, which serves as the heart's natural pacemaker. Neurotransmitters do not have a charge, so choice A is incorrect. Choice C is wrong as overstimulation is not a characteristic of acetylcholine at the sinoatrial node. Choice D is also incorrect because acetylcholine actively influences heart rate regulation when released at the sinoatrial node.
