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. A 60-year-old patient has been treated for pneumonia for the past 6 weeks. The patient is seen today in the clinic for an unexplained weight loss of 10 pounds over the last 6 weeks. Which is an appropriate rationale for this patient's weight loss?

A. Chronic diseases such as hypertension do not usually cause weight loss.
B. Weight loss is more likely due to underlying medical conditions than unhealthy eating habits.
C. Unexplained weight loss often accompanies short-term illnesses.
D. Weight loss is not typically caused by mental health dysfunctions.

Correct answer: C

Rationale: Unexplained weight loss in a patient with pneumonia could indicate an underlying short-term illness or a chronic condition like endocrine disease, malignancy, depression, anorexia nervosa, or bulimia. Hypertension is not commonly associated with weight loss; it usually leads to weight gain due to fluid retention. Unhealthy eating habits are less likely to explain significant unexplained weight loss over a short period. Mental health dysfunctions can affect appetite but are not typically primary causes of significant unexplained weight loss.

3. The healthcare professional has collected the following information on a patient: palpated blood pressure"?180 mm Hg; auscultated blood pressure"?170/100 mm Hg; apical pulse"?60 beats per minute; radial pulse"?70 beats per minute. What is the patient's pulse pressure?

A. 10
B. 70
C. 80
D. 100

Correct answer: B

Rationale: Pulse pressure is the numerical difference between the systolic and diastolic blood pressure readings. In this case, the systolic blood pressure is 170 mm Hg, and the diastolic blood pressure is 100 mm Hg. Therefore, the pulse pressure is calculated as 170 - 100 = 70 mm Hg. Pulse pressure reflects the stroke volume, the amount of blood ejected from the heart with each beat. Choices A, C, and D are incorrect because they do not accurately represent the difference between the systolic and diastolic blood pressure readings provided.

4. Mr. Thomas is a well-groomed 68-year-old male patient who had prostate surgery two days ago. He has an indwelling catheter and a urinary drainage bag. You have weighed him at 9 am each morning for 3 mornings in a row. Today, on the 4th day, his morning weight is 3 pounds more than it was the day before. Why could he have gained these 3 pounds in one day, on a 1000 calorie diet?

A. It is obvious that his visitors have been sneaking him junk food from the local fast-food restaurant.
B. It may be that his urinary drainage bag was not emptied today and it was emptied on previous days.
C. It is obvious that the scale is broken and it should be replaced immediately to prevent these false weights.
D. A 3-pound weight gain is not significant enough to question and should just be noted.

Correct answer: B

Rationale: The correct answer is that the weight gain may be due to the urinary drainage bag not being emptied today, while it was emptied on previous days. This scenario is common and can lead to an increase in weight that is not related to food intake. Choice A is incorrect because assuming visitors are sneaking junk food is speculative and not based on facts. Choice C is incorrect as there is no evidence to suggest the scale is broken. Choice D is incorrect because any unexplained weight gain should be investigated further, even if it seems insignificant at first.

5. When assessing a 75-year-old patient who has asthma, the nurse notes that the patient assumes a tripod position, leaning forward with arms braced on the chair. How would the nurse interpret these findings?

A. Interpret that the patient is eager and interested in participating in the interview.
B. Evaluate the patient for abdominal pain, which may be exacerbated in the sitting position.
C. Interpret that the patient is having difficulty breathing and assist them to a supine position.
D. Recognize that a tripod position is often used when a patient is having respiratory difficulties.

Correct answer: D

Rationale: Assuming a tripod position"?leaning forward with arms braced on chair arms"?occurs with chronic pulmonary diseases like asthma. This position helps improve breathing by allowing better use of respiratory muscles. Option A is incorrect because assuming the tripod position is not related to being eager or interested in participating in an interview. Option B is incorrect as abdominal pain is not typically associated with the tripod position in this context. Option C is incorrect as assisting the patient to a supine position would not address the underlying respiratory difficulty indicated by the tripod position. Therefore, the correct interpretation is to recognize that the patient is likely experiencing respiratory difficulties when assuming the tripod position.
