Nursing Elites

1. A client is having blood tests and has an elevated lymphocyte level. Based on knowledge of cellular components, what does the nurse know about these cells?

• A. Contain histamine and provide protection during allergic reactions
• B. Are involved in phagocytosis
• C. Provide protection and immunity against foreign substances
• D. Carry hemoglobin and oxygen to body tissues

Correct answer: C

Rationale: Lymphocytes are a type of white blood cells that play a crucial role in supporting the body's immune system. They are responsible for producing substances that protect the body against infections and foreign substances that could potentially harm the client. Lymphocytes consist of two main types: T cells, which are produced in the thymus, and B cells, which are produced in the lymphatic tissue. Choice A is incorrect because histamine is mainly associated with basophils and mast cells, not lymphocytes. Choice B is incorrect as phagocytosis is a function of other white blood cells such as neutrophils and macrophages. Choice D is also incorrect as carrying hemoglobin and oxygen is a function of red blood cells, not lymphocytes.

2. OSHA has very strict standards for hospital employees who may encounter hazardous materials or patients who have been exposed to them. These regulations include all of the following EXCEPT:

• A. Respiratory protection must be provided to all employees who might be exposed.
• B. Training on respiratory protection must be provided.
• C. Employers must provide personal protective equipment to all employees.
• D. All ED personnel must be trained in decontamination procedures.

Correct answer: D

Rationale: OSHA regulations for hospital employees dealing with hazardous materials or exposed patients require respiratory protection for potentially exposed employees, training on respiratory protection, and the provision of personal protective equipment. However, not all ED personnel are required to be trained in decontamination procedures. While all ED staff should have a basic understanding of hazmat situations, specific training in decontamination procedures is only necessary for those who will be directly involved in the decontamination process. Therefore, the correct answer is that all ED personnel must be trained in decontamination procedures, as this is not a mandatory requirement under OSHA regulations for hospital employees who may encounter hazardous materials or exposed patients.

3. While planning care for a toddler, the nurse teaches the parents about the expected developmental changes for this age. Which statement by the mother shows that she understands the child's developmental needs?

• A. "I want to protect my child from any falls."?
• B. "I will set limits on exploring the house."?
• C. "I understand the need to use those new skills."?
• D. "I intend to keep control over our child."?

Correct answer: C

Rationale: The correct answer is: "I understand the need to use those new skills."? This response indicates that the mother recognizes the importance of allowing the toddler to practice and develop new skills, supporting autonomy and exploration. Setting limits, protecting from falls, and intending to keep control go against the toddler's developmental needs. Toddlers at this stage require opportunities to explore, practice new skills, and gain independence to foster healthy development.

4. A nurse is caring for a client who is post-op day #1 after a total hip replacement. Although the client was alert with a normal affect in the morning, by lunchtime, the nurse notes the client is confused, has slurred speech, and is having trouble with her balance. Her blood glucose level is 48 mg/dl. What is the next action of the nurse?

• A. Contact the physician immediately
• B. Administer a bolus of 50 cc of D20W through the IV
• C. Administer 10 units of regular insulin
• D. Give the client 6 oz. of orange juice

Correct answer: D

Rationale: A client with a blood glucose level of 48 mg/dl is experiencing significant hypoglycemia, as manifested by confusion, balance difficulties, and slurred speech. The nurse should work to correct this situation as rapidly as possible. The first measure that can be performed quickly and will have fast results is to give the client something to eat or drink that contains glucose, such as 6 oz. of orange juice. Administering a bolus of D20W through the IV (Choice B) would be too aggressive and could lead to complications in this scenario. Administering regular insulin (Choice C) would further lower the blood glucose level, worsening the client's symptoms. Contacting the physician (Choice A) is important, but immediate intervention to raise the blood glucose level is crucial to address the client's hypoglycemia.

5. When a blood pressure cuff is too wide for a client's arm, what type of reading might this blood pressure cuff produce?

• A. A normal reading
• B. An abnormally low reading
• C. An abnormally high reading
• D. A fluctuating reading

Correct answer: B

Rationale: When a blood pressure cuff is too wide for a client's arm, it may produce an abnormally low blood pressure reading. This occurs because the oversized cuff can lead to an underestimation of blood pressure. It is essential to ensure that the cuff fits appropriately to obtain an accurate reading. An abnormally high reading (Choice C) is less likely with an oversized cuff, as it generally leads to lower readings. A normal reading (Choice A) is unlikely due to the inaccuracies caused by the oversized cuff. A fluctuating reading (Choice D) is not a typical result of using a cuff that is too wide; instead, it usually leads to consistently low readings.
