Pharmacology and the Nursing Process 10th Edition Test Bank

Correct Answer: A

Rationale: The correct answer is A because shampooing the hair thoroughly helps remove oil and dirt, which can interfere with the CT scan results. By having clean hair, the scan can produce clearer images. Choice B is incorrect because some preparation is needed for a CT scan, especially regarding cleanliness. Choice C is incorrect as giving a cleansing enema and fluids until 8 AM is not necessary for a CT scan of the head. Choice D is incorrect as shaving the scalp and attaching electrodes are not part of routine preparation for a CT scan.

Correct Answer: D

Rationale: The correct answer is D: Aphasia. Aphasia is a language disorder that affects a person's ability to communicate and understand speech. In this case, Mr. Dela Isla's difficulty in comprehending what the nurse was saying indicates a problem with language processing, which aligns with the symptoms of aphasia. Insomnia (A) is a sleep disorder, not related to language comprehension. Agnosia (B) is a perception disorder where someone cannot recognize objects or people, not related to language. Apraxia (C) is a motor disorder affecting the ability to perform purposeful movements, not related to language comprehension.

Correct Answer: B

Rationale: The correct answer is B (AB). AB blood type is the rarest because it is a result of inheriting both A and B alleles, making it less common in the population. AB individuals can only receive blood from other AB individuals due to their unique antigens. Blood types A, B, and O are more common in the population, with O being the most common as it is the universal donor. Blood type A and B are more common than AB since they only require one allele for their respective antigens. Thus, the rarity of AB blood type is due to the inheritance of both A and B alleles, making it the least common among the choices provided.

Correct Answer: C

Rationale: The correct answer is C: Clinical pathways. Clinical pathways are standardized, evidence-based interdisciplinary plans of care used in case management to guide the treatment and management of clients. They outline the expected course of treatment, interventions, and outcomes for specific health conditions. Kardex care plans (A) are outdated paper-based patient information systems, not specifically for interdisciplinary care plans. Computerized plans of care (B) may refer to electronic health records but do not necessarily imply standardized interdisciplinary plans. Student care plans (D) are educational tools for students and not typically used in case management for clients.

Correct Answer: B

Rationale: The correct answer is B: Tachycardia. Levothyroxine is a synthetic form of thyroid hormone used to treat hypothyroidism. If the dose is too high, it can lead to symptoms of hyperthyroidism, including tachycardia (rapid heartbeat). This is because an excess of thyroid hormone can increase the heart rate. Dysuria (choice A) is not a common adverse effect of levothyroxine. Leg cramps (choice C) are more commonly associated with electrolyte imbalances. Blurred vision (choice D) is not a typical adverse effect of levothyroxine.
