NCLEX RN Exam Review Answers
1. A client is admitted for a head injury. His body is lying in an abnormal position and the physician states he is exhibiting decorticate posturing. Based on this assessment, the nurse can expect to find the client with:
- A. The legs extended and rotated internally; the elbow, wrists, and fingers flexed
- B. The legs pulled toward the chest; the head bent back at a 30-degree angle
- C. The back arched; the arms and legs extended and rigid
- D. The legs extended and rotated externally; the head turned to the right or the left
Correct answer: A
Rationale: Decorticate posturing is indicative of an injury to the corticospinal tract, resulting in abnormal posturing. It may occur spontaneously or in response to stimulation. This posture involves the legs being extended and rotated internally, while the elbows, wrists, and fingers are flexed inward. Choice A is correct because it accurately describes the expected positioning associated with decorticate posturing. Choices B, C, and D are incorrect. Choice B describes a different type of posturing known as opisthotonos. Choice C describes an exaggerated arching of the back, which is not characteristic of decorticate posturing. Choice D describes a different type of posturing with external rotation of the legs and head turning to the side, not consistent with decorticate posturing.
2. A patient's chart indicates a history of ketoacidosis. Which of the following would you not expect to see with this patient if this condition were acute?
- A. Vomiting
- B. Extreme Thirst
- C. Weight gain
- D. Acetone breath smell
Correct answer: C
Rationale: In acute ketoacidosis, a patient typically experiences rapid weight loss due to the body burning fat and muscle for energy in the absence of sufficient insulin. Therefore, weight gain would not be expected. Vomiting may occur due to the metabolic disturbances associated with ketoacidosis. Extreme thirst is a common symptom as the body tries to compensate for dehydration. Acetone breath smell is a classic sign of ketoacidosis as acetone is one of the ketones produced during this condition.
3. A mother brings her 26-month-old to the well-child clinic. She expresses frustration and anger due to her child's constant saying 'no' and refusal to follow her directions. The nurse explains this is normal for his age, as negativism is attempting to meet which developmental need?
- A. Trust
- B. Initiative
- C. Independence
- D. Self-esteem
Correct answer: C
Rationale: In Erikson's theory of development, toddlers struggle to assert independence. They often use the word 'no' even when they mean yes. This stage is called autonomy versus shame and doubt. The child's behavior of saying 'no' and resisting directions reflects the developmental need for independence, not trust (option A), initiative (option B), or self-esteem (option D). Trust is typically associated with early infancy, initiative with preschool age, and self-esteem with later childhood and adolescence.
4. Which of the following glands found in the skin secretes a liquid called Sebum?
- A. Apocrine Glands
- B. Sebaceous Glands
- C. Lacrimal Glands
- D. Sweat Glands
Correct answer: B
Rationale: Sebum is a liquid secreted by glands in the skin known as sebaceous glands. Sebum's primary function is to lubricate the skin and help maintain its integrity. Apocrine glands secrete a different type of sweat that is odorless but can develop an odor when combined with bacteria on the skin. Lacrimal glands produce tears to keep the eyes moist, and sweat glands secrete sweat to regulate body temperature through evaporation. Therefore, the correct answer is Sebaceous Glands because they specifically secrete sebum, distinguishing them from the other gland types mentioned.
5. The nurse is performing tuberculosis (TB) skin tests in a clinic that has many patients who have immigrated to the United States. Which question is most important for the nurse to ask before the skin test?
- A. Is there any family history of TB?
- B. How long have you lived in the United States?
- C. Do you take any over-the-counter (OTC) medications?
- D. Have you received the bacille Calmette-Guerin (BCG) vaccine for TB?
Correct answer: D
Rationale: It is crucial for the nurse to inquire about whether the patient has received the bacille Calmette-Guerin (BCG) vaccine for TB before performing the skin test. Patients who have received the BCG vaccine can have a positive Mantoux test, leading to the need for alternative screening methods, such as a chest x-ray, to determine TB infection. While family history of TB and length of time in the United States are relevant factors, they do not directly impact the decision to perform the TB skin test. Asking about over-the-counter medications, unless relevant to TB treatment, is not as critical as assessing BCG vaccination status.
