1. Which of the following statements best describes footdrop?

A. The foot is permanently fixed in the dorsiflexion position
B. The foot is permanently fixed in the plantar flexion position
C. The toes of the foot are permanently fanned
D. The heel of the foot is permanently rotated outward

Correct answer: B

Rationale: Footdrop results in the foot becoming permanently fixed in a plantar flexion position, not dorsiflexion. This position points the toes downward. The client may be unable to put weight on the foot, making ambulation difficult. Footdrop can be caused by immobility or chronic illnesses that cause muscle changes, such as multiple sclerosis or Parkinson's disease. Choice A is incorrect because footdrop leads to plantar flexion, not dorsiflexion. Choice C is incorrect as it describes a different condition known as 'toe fanning.' Choice D is incorrect as it describes an external rotation of the heel, which is not a characteristic of footdrop.

2. The instructor is teaching a class on basic assessment skills. Which of the following statements is true regarding the stethoscope and its use?

A. Slope of the earpieces should point forward toward the examiner's nose.
B. It blocks out extraneous room noise but does not magnify sound.
C. The tubing length should be 14 to 18 inches to prevent sound distortion.
D. Both fit and quality of the stethoscope are important.

Correct answer: B

Rationale: The stethoscope does not magnify sound but effectively blocks out extraneous room noises. The correct orientation of the earpieces is with the slope pointing forward toward the examiner's nose, not posteriorly. The tubing length of a stethoscope should ideally be between 14 to 18 inches (36 to 46 cm) to avoid sound distortion. Using tubing longer than this range can distort sound. Both the fit and quality of the stethoscope are crucial for accurate auscultation and assessment, highlighting their significance in clinical practice. Therefore, the correct answer is that the stethoscope blocks out extraneous room noise but does not magnify sound.

3. While percussing over the liver of a patient, the nurse notices a dull sound. What should the nurse do?

A. Consider this a normal finding
B. Palpate this area for an underlying mass
C. Reposition the hands and attempt to percuss in this area again
D. Consider this finding as abnormal and refer the patient for additional treatment

Correct answer: A

Rationale: When percussing over relatively dense organs, such as the liver or spleen, a dull sound is a normal finding due to the organ's density. This occurs because the sound waves produced by tapping on the organ travel through the dense tissue, resulting in a dull sound. Therefore, the correct action for the nurse in this scenario is to consider a dull sound over the liver as a normal finding. Palpating for an underlying mass (Choice B) is not indicated based on the percussion finding alone. Repositioning the hands and repeating the percussion (Choice C) may not change the dull sound over the liver. Referring the patient for additional treatment (Choice D) without understanding the normal percussion findings over the liver would be premature. Thus, the most appropriate action is to interpret the dull sound as a normal finding.

4. When assessing the pulse of a 6-year-old patient, the nurse notices that the heart rate varies with the respiratory cycle, speeding up at the peak of inspiration and slowing to normal with expiration. What action would the nurse take next?

A. Notify the physician.
B. Record this finding as normal.
C. Check the child's blood pressure and note any variation with respiration.
D. Document that this child has bradycardia and continue with the assessment.

Correct answer: B

Rationale: The correct action for the nurse to take next is to record this finding as normal. Sinus dysrhythmia, characterized by heart rate variation with the respiratory cycle, is commonly found in children and young adults. The heart rate speeds up at the peak of inspiration and slows to normal with expiration. This phenomenon is a normal variant and does not require any intervention. There is no need to notify the physician as this finding is within the expected range for this age group. Checking the child's blood pressure for variations with respiration or documenting the child as having bradycardia would not be appropriate in this case, as sinus dysrhythmia is a normal physiological response.

5. A client on the nursing unit is terminally ill but remains alert and oriented. Three days after admission, the nurse observes signs of depression. The client states, 'I'm tired of being sick. I wish I could end it all.' What is the most accurate and informative way to record this data in a nursing progress note?

A. Client appears to be depressed, possibly suicidal
B. Client reports being tired of being ill and wants to die
C. Client does not want to live any longer and is tired of being ill
D. Client states, 'I'm tired of being sick. I wish I could end it all.'

Correct answer: D

Rationale: Subjective data includes thoughts, beliefs, feelings, perceptions, and sensations that are apparent only to the person affected and cannot be measured, seen, or felt by the nurse. This information should be documented using the client's exact words in quotes. The other options indicate that the nurse has drawn the conclusion that the client no longer wishes to live. From the data provided, the cues do not support this assumption. A more complete assessment should be conducted to determine if the client is suicidal.
