1. A person who had a left CVA and right lower extremity hemiparesis is being instructed by a nurse to use a quad cane. Which of the following is the most appropriate gait sequence?
- A. Place the cane in the patient's left upper extremity, encourage cane, then right lower extremity, then left upper extremity gait sequence.
- B. Place the cane in the patient's left upper extremity, encourage cane, then left lower extremity, then right upper extremity gait sequence.
- C. Place the cane in the patient's right upper extremity, encourage cane, then right lower extremity, then left upper extremity gait sequence.
- D. Place the cane in the patient's right upper extremity, encourage cane, then left lower extremity, then right upper extremity gait sequence.
Correct answer: A
Rationale: The correct gait sequence for a person with left CVA and right lower extremity hemiparesis using a quad cane is to place the cane in the patient's strong upper extremity, which is the left upper extremity in this case. The correct sequence should be right lower extremity followed by left upper extremity, as this pattern mimics a normal gait pattern. Therefore, Choice A is the correct answer. Choices B, C, and D are incorrect because they do not follow the proper gait sequence for this specific patient's condition. The cane should be placed in the strong upper extremity, and the affected lower extremity should move first to provide stability and support, which is essential in this situation.
2. The client has just returned from electroconvulsive therapy (ECT) and is very drowsy. What is the position of choice until the client regains full consciousness?
- A. Supine
- B. Fowlers
- C. Lateral
- D. High Fowlers
Correct answer: C
Rationale: The correct answer is 'Lateral.' When a client is very drowsy or sedated, placing them in the lateral position is important to maintain an open airway and allow for drainage of secretions. This position helps prevent airway obstruction and aspiration. Choice A, 'Supine,' is lying flat on the back and may not be ideal for a drowsy client due to the risk of airway compromise. Choice B, 'Fowlers,' is a semi-sitting position that is beneficial for clients with respiratory distress, but it may not be the best choice for a very drowsy individual. Choice D, 'High Fowlers,' is a more upright sitting position, which again may not be suitable for a drowsy client as it does not facilitate airway patency as effectively as the lateral position.
3. 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.
4. Chemotherapeutic agents often produce a degree of myelosuppression including leukopenia. Leukopenia does not present immediately but is delayed several days or weeks because:
- A. the client's hemoglobin and hematocrit are normal.
- B. red blood cells are affected first.
- C. folic acid levels are normal.
- D. the current white cell count is not affected by chemotherapy.
Correct answer: D
Rationale: Leukopenia does not present immediately after chemotherapy because time is required to clear circulating cells before the effect on precursor cell maturation in the bone marrow becomes evident. Leukopenia is characterized by an abnormally low white blood cell count. The correct answer is D because the white cell count is not immediately affected by chemotherapy. Choices A, B, and C are incorrect as they pertain to red blood cells (hemoglobin and hematocrit), which are not directly related to the delayed onset of leukopenia.
5. The nurse is checking laboratory values on a patient who has crackling rales in the lower lobes, 2+ pitting edema, and dyspnea with minimal exertion. Which of the following laboratory values does the nurse expect to be abnormal?
- A. Potassium.
- B. B-type natriuretic peptide (BNP).
- C. C-reactive protein (CRP).
- D. Platelets.
Correct answer: B
Rationale: The client's symptoms suggest heart failure. BNP is a neurohormone released from the ventricles due to increased pressure and stretch, as seen in heart failure. A BNP level greater than 51 pg/mL is often associated with mild heart failure, with higher levels indicating more severe heart failure. Potassium levels are not typically affected by heart failure. CRP is an inflammation indicator used to predict coronary artery disease risk, not directly related to heart failure in this case. The client's symptoms do not suggest bleeding or clotting abnormalities associated with platelet count issues, making platelets an unlikely abnormal value.
