A healthcare professional is reviewing a patient's current Lithium levels. Which of the following values is outside the therapeutic range?
- A. 1.0 mEq/L
- B. 1.1 mEq/L
- C. 1.2 mEq/L
- D. 1.3 mEq/L
Correct Answer: D
Rationale: The correct answer is 1.3 mEq/L. The therapeutic range for Lithium levels typically falls between 0.6 to 1.2 mEq/L. Values below or above this range can lead to suboptimal treatment outcomes or toxicity. Choices A, B, and C are within the therapeutic range of 1.0-1.2 mEq/L, making them appropriate levels for patient care.

Which of the following diseases or conditions is least likely to be associated with an increased potential for bleeding?
- A. metastatic liver cancer
- B. gram-negative septicemia
- C. pernicious anemia
- D. iron-deficiency anemia
Correct Answer: C
Rationale: Pernicious anemia is least likely to be associated with an increased potential for bleeding. Pernicious anemia results from vitamin B12 deficiency due to a lack of intrinsic factor, leading to faulty absorption from the gastrointestinal tract. While pernicious anemia can lead to other health issues, bleeding tendencies are not a primary concern. Metastatic liver cancer (choice A) can cause liver dysfunction leading to decreased synthesis of clotting factors, increasing the risk of bleeding. Gram-negative septicemia (choice B) can lead to disseminated intravascular coagulation (DIC) causing excessive bleeding. Iron-deficiency anemia (choice D) can result in microcytic hypochromic red blood cells, which can impair oxygen transport and lead to tissue hypoxia, but it is not directly associated with a significant potential for bleeding.
A patient has recently been prescribed Zidovudine (Retrovir). The patient has AIDS. Which of the following side effects should the patient specifically watch out for?
- A. Weakness and SOB
- B. Fever and anemia
- C. Hypertension and SOB
- D. Fever and hypertension
Correct Answer: B
Rationale: The correct answer is 'Fever and anemia.' Zidovudine (Retrovir) is known to cause anemia as a side effect due to its impact on the bone marrow. Fever is also a common side effect associated with Zidovudine use. Therefore, the patient should watch out for these specific side effects. Choice A (Weakness and SOB) is incorrect as shortness of breath (SOB) is not a commonly reported side effect of Zidovudine. Choice C (Hypertension and SOB) and Choice D (Fever and hypertension) are unrelated to the known side effects of Zidovudine, making them incorrect.
What is appropriate care for a client with neutropenia?
- A. Avoiding fresh fruits and vegetables.
- B. Having a private room.
- C. Wearing a mask when out of the room.
- D. Practicing routine hand washing.
Correct Answer: C
Rationale: When a client has neutropenia, they have low white blood cell levels, which increases the risk of infections due to a weakened immune system. Wearing a mask when out of the room is crucial to reduce the risk of exposure to respiratory infections. Avoiding fresh fruits and vegetables is also necessary as they may contain harmful pathogens. Having a private room helps minimize exposure to pathogens and ensures that visitors are carefully screened for any signs of illness. Routine hand washing is essential to prevent the spread of infections in the healthcare setting, but the most direct measure to protect the client from potential infections is wearing a mask when out of the room.
A nurse working in a pediatric clinic observes bruises on the body of a four-year-old boy. The parents report the boy fell while riding his bike. The bruises are located on his posterior chest wall and gluteal region. What should the nurse do?
- A. Suggest a script for counseling the family to the doctor on duty.
- B. Recommend a warm bath for the boy to decrease healing time.
- C. Notify the case manager in the clinic about possible child abuse concerns.
- D. Recommend ROM exercises to the patient's spine to decrease healing time.
Correct Answer: C
Rationale: In this scenario, the nurse is observing bruises on a child's body that are located in areas not commonly associated with accidental injuries. Given the concerning nature of the bruising pattern and the inconsistent history provided by the parents, the nurse should suspect possible child abuse and take appropriate action by notifying the case manager in the clinic. The safety and well-being of the child should always be the top priority. Counseling for the family, warm baths, or recommending range of motion (ROM) exercises are not appropriate actions in this situation and may not address the underlying issue of potential child abuse.
Which of the following infant behaviors demonstrates the concept of object permanence?
- A. The infant cries when his mother leaves the room.
- B. The infant looks at the floor to find a toy that he was playing with and dropped.
- C. The infant picks up another toy after the one he was playing with rolls under the couch.
- D. The infant participates in a game of patty-cake.
Correct Answer: B
Rationale: Object permanence occurs when the infant learns that something or someone still exists even though they might not be able to see it or them. This typically develops between 9 and 10 months of age. The correct answer, 'The infant looks at the floor to find a toy that he was playing with and dropped,' demonstrates object permanence as the infant understands that the toy still exists even though it is temporarily out of sight. Choices A and C do not directly relate to object permanence as the behaviors described do not necessarily indicate an understanding of objects existing when out of sight. Choice D is incorrect as participating in a game of patty-cake does not involve demonstrating object permanence. Peek-a-boo is a more suitable example of a game that demonstrates object permanence, as the infant continues to look for the hidden face, understanding that it still exists even though temporarily unseen.
