A client with osteoarthritis of the hips and knees has received instructions on how to use a walker for ambulation.
Which behavior observed by the nurse indicates the client understands the instructions?
The client uses the walker to get up from the chair and looks down at his feet to prevent falling.
The client bears weight on both feet when moving the walker ahead and steps with the weaker leg first.
The client places her full weight on the walker with her arms while taking steps to prevent pressure on her lower extremity joints.
The client leans forward at a 60-degree angle while stepping into the walker but looks ahead at where he is going.
The Correct Answer is B
The client bears weight on both feet when moving the walker ahead and steps with the weaker leg first. This is the proper way to use a walker for ambulation, as it provides stability and reduces stress on the affected joints.
Choice A is wrong because the client should not look down at his feet to prevent falling, but rather look ahead at where he is going. Looking down can cause neck strain and loss of balance.
Choice C is wrong because the client should not place her full weight on the walker with her arms while taking steps, as this can cause upper extremity fatigue and injury. The client should use the walker as a support, not a crutch.
Choice D is wrong because the client should not lean forward at a 60-degree angle while stepping into the walker, as this can cause back pain and poor posture. The client should stand upright and move the walker forward about one step’s length at a time.

Correct Answer is A
Explanation
Using an automatic BP cuff with a shivering client with a history of an irregular heart rate can result in inaccurate and low readings.
This is because shivering can interfere with the cuff inflation and deflation, and an irregular heart rate can affect the accuracy of the device.
The nurse should intervene and use a manual BP cuff with a stethoscope instead.
Choice B is wrong because pulling the client’s ear pinna backward, up and out to obtain a tympanic membrane temperature is the correct technique for adults and older children. This helps to straighten the ear canal and allow the light to reflect on the tympanic membrane, which shares the same vascular artery as the hypothalamus.
Choice C is wrong because counting the client’s radial pulse who is supine with the forearm straight alongside the body is an appropriate method.
The radial pulse can be easily palpated at the wrist, and the supine position and straight forearm do not affect the pulse rate.
Choice D is wrong because counting the respirations for one full minute for a client with tachypnea is a recommended practice.
Tachypnea means rapid breathing, and counting for one full minute can ensure accuracy and detect any variations in the respiratory pattern.
Correct Answer is A
Explanation
An idiosyncratic drug effect is an unpredictable and uncommon reaction to a drug that is not related to the dose, the pharmacology, or the patient’s allergy or intolerance. It may be caused by genetic factors, metabolic abnormalities, or interactions with other drugs or substances. An example of an idiosyncratic drug effect is paradoxical agitation or excitement after receiving a sedative.
B. A toxic drug effect is a harmful reaction to a drug that is related to the dose or the pharmacology of the drug. It may cause symptoms such as nausea, vomiting, drowsiness, confusion, or respiratory depression. A toxic drug effect is unlikely to cause agitation after receiving a sedative unless there is an overdose or a drug interaction that increases the level of the sedative in the blood.
C. An allergic drug response is an immunological reaction to a drug that is not related to the dose or the pharmacology of the drug. It may cause symptoms such as rash, itching, swelling, fever, or anaphylaxis. An allergic drug response is unlikely to cause agitation after receiving a sedative unless there is a severe anaphylactic reaction that affects the brain or the circulation.
D. An unexpected drug interaction is a modification of the effect of one drug by another drug or substance that is not predictable based on their pharmacology. It may cause an increase or a decrease in the efficacy or toxicity of one or both drugs. An unexpected drug interaction may cause agitation after receiving a sedative if there is a synergistic effect that enhances the central nervous system stimulation of another drug or substance (such as caffeine, cocaine, or amphetamines) or if there is an antagonistic effect that reduces the central nervous system depression of the sedative (such as flumazenil, naloxone, or physostigmine). However, these interactions are usually known and avoidable by checking the patient’s history and medication list.
