1. When caring for a 7-week-old infant with hypothyroidism, the nurse explains that the prevention of what complication is dependent on the administration of oral thyroid replacement therapy and is critical for the child?
- A. Excessive growth
- B. Cognitive impairment
- C. Damage to the nervous system
- D. Damage to the urinary system
Correct answer: B
Rationale: The correct answer is B: Cognitive impairment. The treatment of choice for congenital and acquired hypothyroidism is oral thyroid hormone replacement therapy. Prompt treatment is especially critical in the infant with congenital hypothyroidism to avoid permanent cognitive impairment. Excessive growth (Choice A) is not a common complication of hypothyroidism in infants. Damage to the nervous system (Choice C) and damage to the urinary system (Choice D) are not typically associated with untreated hypothyroidism in infants.
2. Humans begin life as a single cell that divides repeatedly. This cell is known as a(n):
- A. zygote.
- B. gonadotrope.
- C. embryo.
- D. chromaffin.
Correct answer: A
Rationale: A zygote is the correct answer. It is the initial cell formed when a sperm cell fertilizes an egg cell, marking the beginning of human development. Choice B, gonadotrope, is incorrect as it refers to a type of hormone-secreting cell in the pituitary gland. Choice C, embryo, is incorrect as it is the stage of development after the zygote has implanted into the uterine wall and undergone initial cell divisions. Choice D, chromaffin, is incorrect as it refers to cells found in the adrenal medulla that produce and store catecholamines.
3. While being educated by a nurse, an assistive personnel (AP) is learning about proper hand hygiene. Which statement made by the AP indicates a good understanding of the teaching?
- A. There are times I should use soap and water rather than alcohol-based hand rub to clean my hands.
- B. I can use alcohol-based hand rub after using the restroom.
- C. Soap and water are only necessary if my hands are visibly dirty.
- D. Hand rub is always sufficient, regardless of the situation.
Correct answer: C
Rationale: Choice C is the correct answer because it demonstrates an understanding that soap and water should be used when hands are visibly dirty or when dealing with specific pathogens. Choice A is incorrect because it suggests the use of soap and water over alcohol-based hand rub without specifying the circumstances. Choice B is incorrect as it implies that using alcohol-based hand rub after using the restroom is always suitable. Choice D is incorrect because it states that hand rub is always enough, which is not true when hands are visibly soiled or when specific pathogens are present.
4. The healthcare professional is preparing client teaching materials on commonly used medications. Which client is most likely to benefit from a client education package about simvastatin?
- A. A 50-year-old male with a history of angina
- B. A 75-year-old male with bone cancer
- C. An 18-year-old pregnant female with diabetes
- D. A 40-year-old female with frequent vaginal infections
Correct answer: A
Rationale: Simvastatin is a medication used to lower cholesterol levels and prevent cardiovascular diseases. It is commonly prescribed for individuals at risk of heart-related conditions. Angina is a symptom of underlying heart disease, and individuals with this condition would benefit most from simvastatin to help manage their cholesterol levels and reduce the risk of cardiovascular events. Therefore, the 50-year-old male with a history of angina is the most suitable candidate for client education regarding simvastatin. Choices B, C, and D are not the most appropriate candidates for simvastatin education because bone cancer, pregnancy with diabetes, and frequent vaginal infections are not conditions typically treated with simvastatin.
5. After receiving a report, the nurse receives the laboratory values for four clients. Which client requires the nurse’s immediate intervention? The client who is...
- A. Short of breath after a shower and has a hemoglobin of 8 grams
- B. Bleeding from a finger stick and has a prothrombin time of 30 seconds
- C. Febrile and has a WBC count of 14,000/mm3
- D. Trembling and has a glucose level of 50 mg/dL
Correct answer: D
Rationale: A glucose level of 50 mg/dL is indicative of hypoglycemia, which requires immediate intervention to prevent further complications. Hypoglycemia can lead to serious consequences such as altered mental status, seizures, and even coma if not promptly addressed. The other options do not present immediate life-threatening conditions that require urgent intervention. Shortness of breath with a hemoglobin of 8 grams may indicate anemia but does not require immediate intervention. Bleeding from a finger stick with a prothrombin time of 30 seconds may suggest clotting issues, which are important but not as immediately critical as hypoglycemia. Being febrile with an elevated WBC count could indicate infection, which is concerning but not as urgently critical as hypoglycemia.
