1. Which of the following characteristics is common in both malignant and benign tumors?

• A. Uncontrolled cell growth
• B. Rapid growth
• C. Metastasis
• D. Invasion of surrounding tissue

Correct answer: A

Rationale: The correct answer is A: Uncontrolled cell growth. This characteristic is common to both malignant and benign tumors. Benign tumors are non-cancerous growths that do not invade nearby tissue or spread to other parts of the body. Therefore, choices B, C, and D are incorrect. Rapid growth, metastasis, and invasion of surrounding tissue are characteristics typically associated with malignant tumors.

2. A hospital client is at a high risk of developing bacterial endocarditis. Which of the following prophylactic measures is likely to be most effective?

• A. Avoiding exposure to individuals known to carry the streptococcus bacterium
• B. Daily administration of low-dose corticosteroids
• C. Prophylactic antimicrobial therapy before any invasive procedure
• D. Routine vaccinations against meningococcal and pneumococcal infections

Correct answer: C

Rationale: Prophylactic antimicrobial therapy before any invasive procedure is the most effective measure in preventing bacterial endocarditis in at-risk individuals. This measure helps to reduce the risk of bacterial infection during invasive procedures, which can lead to endocarditis. Choice A is incorrect as avoiding exposure to individuals with streptococcus does not address the primary preventive measure needed. Choice B is incorrect as corticosteroids do not prevent bacterial endocarditis, and daily administration is not the recommended prophylactic measure. Choice D is incorrect as routine vaccinations against meningococcal and pneumococcal infections are important for other conditions but not specifically for preventing bacterial endocarditis.

3. 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.

4. A woman is complaining that she feels like the room is spinning even though she is not moving. Which of the following is characteristic of benign positional vertigo?

• A. It usually occurs with a headache.
• B. Pupillary changes are common.
• C. It is usually triggered when the patient bends forward.
• D. Nystagmus continues even when the eyes fixate on an object.

Correct answer: C

Rationale: The correct answer is C: 'It is usually triggered when the patient bends forward.' Benign positional vertigo is often triggered by changes in head position, such as bending forward. Choices A, B, and D are incorrect. A is incorrect because benign positional vertigo is not typically associated with headaches. B is incorrect because pupillary changes are not a common feature of benign positional vertigo. D is incorrect because nystagmus in benign positional vertigo usually stops when the eyes fixate on an object.

5. When a child jumps out of the tub, crying and stating her feet are 'burning,' what pathophysiologic principle is responsible for this response?

• A. Pain receptors (nociceptors) have been activated in response to a thermal stimulus.
• B. The child's skin thermal receptors have undergone adaptation.
• C. The child is exhibiting a psychogenic pain response due to anxiety.
• D. The child is experiencing a conditioned pain response based on previous experiences.

Correct answer: A

Rationale: The child's reaction is due to the activation of nociceptors, which are pain receptors that respond to thermal stimuli. This response is an immediate protective mechanism to prevent tissue damage caused by extreme temperatures. Option B is incorrect because adaptation does not explain the child's immediate and intense response. Option C is incorrect as there is a clear physical stimulus present, ruling out a psychogenic response. Option D is incorrect as the child's response is not based on previous experiences but rather on the current thermal stimulus.
