NCLEX RN Exam Review Answers
1. You are caring for an infant who is just about 12 months old. Which assessment data is normal for the infant at this age?
- A. The infant had doubled their birth weight at twelve months.
- B. The infant had tripled their birth weight at twelve months.
- C. The mother reports that the infant is drinking 60 mLs per kilogram of its body weight.
- D. The infant had grown � inch since last month.
Correct answer: A
Rationale: The normal assessment data for the infant at 12 months of age is that the infant has doubled their birth weight at 12 months of age. The mother's reports that the infant is drinking 60 mLs per kilogram of its body weight and the fact that the infant had grown � inch since last month are not normal assessment data. Infants are fed breast milk or formula every two to four hours with a total daily intake of 80 to 100 mLs per kilogram of body weight. As the neonate grows, they gain five to seven ounces during the first six months and then they double their birth weight during the first year; the head circumference increases a half inch each month for six months and then two tenths of an inch until the infant is one year of age. Similarly, the height or length of the newborn increases an inch a month for the first 6 months and then 1/2 inch a month until the infant is 1 year of age.
2. Asepsis is defined as ________________.
- A. the absence of all microorganisms
- B. the absence of disease-causing germs
- C. a urinary infection
- D. a pathogenic infection
Correct answer: B
Rationale: Asepsis is defined as the absence of disease-causing germs. It is surgical asepsis that is defined as the absence of all microorganisms, including spores. A pathogenic infection is an invasion of the body by a pathogen, or disease-causing germ, and a urinary infection is only one type of infection.
3. A 39-year-old woman presents for treatment of excessive vaginal bleeding after giving birth to twins one week ago. Which nursing diagnosis is most appropriate in this situation?
- A. Knowledge Deficit related to post-partum blood loss
- B. Self-Care Deficit related to post-partum neglect
- C. Fluid Volume Deficit related to post-partum hemorrhage
- D. Body Image Disturbance related to body changes after delivery
Correct answer: C
Rationale: The correct nursing diagnosis in this situation is 'Fluid Volume Deficit related to post-partum hemorrhage.' Post-partum hemorrhage can lead to excessive bleeding, putting the client at risk of fluid volume deficit due to the loss of blood volume. This diagnosis is most appropriate as it addresses the immediate concern of fluid loss. 'Knowledge Deficit related to post-partum blood loss' (Choice A) is incorrect as the priority in this case is addressing the physical issue of fluid volume deficit rather than knowledge deficit. 'Self-Care Deficit related to post-partum neglect' (Choice B) is not relevant to the situation described. 'Body Image Disturbance related to body changes after delivery' (Choice D) is not the most appropriate nursing diagnosis in this context where the primary concern is fluid volume deficit due to post-partum hemorrhage.
4. A client must use a non-rebreathing oxygen mask. Which of the following statements is true regarding this type of mask?
- A. A non-rebreather can provide an FiO2 of 40%.
- B. A client should breathe through his or her mouth when using a non-rebreather.
- C. A non-rebreather offers a reservoir from which the client inhales.
- D. The mask of a non-rebreather should be changed every 3 hours.
Correct answer: A
Rationale: A non-rebreather mask is used for supplemental oxygen delivery for clients experiencing breathing difficulties. The non-rebreather mask includes a one-way valve that allows exhaled air to escape, preventing the rebreathing of carbon dioxide. The client inhales oxygenated air from a reservoir bag attached to the mask, providing high-concentration oxygen therapy. A non-rebreather mask can deliver FiO2 levels of up to 90%, making it an effective intervention for clients requiring high oxygen concentrations. Therefore, the statement that 'A non-rebreather can provide an FiO2 of 40%' is correct. Choices B, C, and D are incorrect because clients should breathe through their nose and mouth, the mask offers a reservoir for inhaling oxygen, and the mask should be assessed and potentially replaced if soiled or damaged, not routinely changed every 3 hours.
5. 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.
