1. 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.

2. What are direct effects of antibodies? (Select ONE that does not apply):

• A. Neutralization
• B. Agglutination
• C. Precipitation
• D. Phagocytosis

Correct answer: D

Rationale: The direct effects of antibodies include neutralization, agglutination, and precipitation. Antibodies neutralize pathogens by binding to them and preventing their harmful effects. Agglutination involves the clumping together of pathogens, making it easier for phagocytes to engulf them. Precipitation refers to the process where antibodies bind to soluble antigens, forming large complexes that are easily removed from the body. Phagocytosis, on the other hand, is an indirect effect of antibodies where phagocytes engulf and destroy pathogens opsonized by antibodies, not a direct effect.

3. A client with a diagnosis of depression has been prescribed a medication that ultimately increases the levels of the neurotransmitter serotonin between neurons. Which process will accompany the actions of the neurotransmitter in a chemical synapse?

• A. Two-way communication between neurons is permitted, in contrast to the one-way communication in electrical synapses.
• B. Communication between a neuron and the single neuron it is connected with will be facilitated.
• C. The neurotransmitter will cross gap junctions more readily.
• D. More neurotransmitters will cross the synaptic cleft and bond with postsynaptic receptors.

Correct answer: D

Rationale: When serotonin levels increase, more neurotransmitters will cross the synaptic cleft and bind with postsynaptic receptors, facilitating enhanced communication. Option A is incorrect because chemical synapses, unlike electrical synapses, are unidirectional. Option B is incorrect because neurotransmitters impact communication with multiple neurons, not just a single connected neuron. Option C is incorrect because neurotransmitters cross the synaptic cleft, not gap junctions.

4. The signs of thyroid crisis resulting from Graves' disease include:

• A. constipation with gastric distension.
• B. bradycardia and bradypnea.
• C. hyperthermia and tachycardia.
• D. constipation and lethargy.

Correct answer: C

Rationale: Thyroid crisis in Graves' disease typically presents with hyperthermia (high body temperature) and tachycardia (rapid heart rate). These symptoms are a result of excessive thyroid hormone production and can lead to life-threatening complications if not promptly addressed. Choices A, B, and D are incorrect because constipation with gastric distension, bradycardia and bradypnea, and constipation and lethargy are not typical signs of a thyroid crisis in Graves' disease.

5. An older adult patient has asked her primary care provider for a prescription that will help to resolve her “warped toenails.” The care provider has diagnosed the woman with onychomycosis. The nurse should anticipate that this patient will be treated with what drug?

• A. Micafungin (Mycamine)
• B. Terbinafine (Lamisil)
• C. Voriconazole (Vfend)
• D. Fluconazole (Diflucan)

Correct answer: B

Rationale: The correct answer is B: Terbinafine (Lamisil). Terbinafine is commonly used to treat onychomycosis, a fungal infection of the toenails or fingernails. It works by stopping the growth of the fungus. Micafungin (Mycamine) is an antifungal medication used for different types of fungal infections but is not typically used to treat onychomycosis. Voriconazole (Vfend) is another antifungal medication used for specific fungal infections, but it is not a first-line treatment for onychomycosis. Fluconazole (Diflucan) is also an antifungal medication, but it is more commonly used for yeast infections and may not be as effective for treating onychomycosis compared to terbinafine.
