1. Which of the following is a negative outcome associated with impaired mobility?

A. Increased amounts of calcium are absorbed from circulation
B. A drop in blood pressure occurs when rising from a sitting to a standing position
C. The amount of mucus in the bronchi and lungs decreases
D. The vessel walls of the circulatory system thicken

Correct answer: B

Rationale: A client with impaired mobility may develop changes in body systems that put them at risk of further illness or injury. One negative outcome associated with impaired mobility is orthostatic hypotension, where blood pressure drops significantly when moving from a sitting or lying position to a standing position. This drop in blood pressure can lead to symptoms such as dizziness or fainting. This occurs because blood circulates more slowly or pools in the distal extremities due to impaired mobility. Choice A is incorrect because increased calcium absorption is not a typical negative outcome associated with impaired mobility. Choice C is incorrect because a decrease in mucus in the bronchi and lungs is not a common negative outcome of impaired mobility. Choice D is incorrect because thickening of vessel walls in the circulatory system is not directly associated with impaired mobility.

2. When is a physician likely to assess turgor?

A. When iron deficiency is suspected.
B. When heart and lung issues are suspected.
C. When dehydration is suspected.
D. None of the above.

Correct answer: C

Rationale: Skin turgor is assessed when dehydration is suspected. To evaluate skin turgor, a physician pinches the skin and observes how quickly it returns to its normal position. If the skin stays folded for an extended period, it indicates dehydration. Assessing turgor helps determine a patient's hydration status. Choice A is incorrect because skin turgor is not used to assess iron deficiency. Choice B is incorrect as turgor is not related to heart and lung issues, but rather hydration status. Choice D is incorrect as turgor assessment is relevant when dehydration is suspected.

3. An adult patient is at the clinic for a physical examination. The patient states that they are feeling 'very anxious' about the physical examination. What steps can the nurse take to make the patient more comfortable?

A. Appear unhurried and confident when examining the patient.
B. Leave the room when the patient undresses unless they need assistance.
C. Ask the patient to change into an examining gown and to leave their undergarments on.
D. Measure vital signs at the beginning of the examination to gradually accustom the patient.

Correct answer: A

Rationale: To help alleviate the patient's anxiety, the nurse should appear unhurried and confident during the examination. This can make the patient feel more at ease and reassured. It is important for the nurse to respect the patient's privacy by leaving the room while the patient changes unless assistance is needed. The patient should be instructed to change into an examining gown while leaving their undergarments on, providing a sense of comfort and familiarity. Additionally, measuring vital signs at the beginning of the examination can help gradually acclimate the patient to the process, making it less overwhelming. Therefore, the correct answer is to appear unhurried and confident when examining the patient. Choices B, C, and D are incorrect because they do not directly address the patient's anxiety or provide comfort in the same way as the correct answer.

4. A child is admitted to the hospital several days after stepping on a sharp object that punctured her athletic shoe and entered the flesh of her foot. The physician is concerned about osteomyelitis and has ordered parenteral antibiotics. Which of the following actions is done immediately before the antibiotic is started?

A. The admission orders are written.
B. A blood culture is drawn.
C. A complete blood count with differential is drawn.
D. The parents arrive.

Correct answer: B

Rationale: Before starting antibiotics, a blood culture should be drawn to identify the causative organism. This step is crucial as antibiotics may interfere with the identification process. Drawing a complete blood count with differential or writing admission orders are important steps in patient care but are not as critical as obtaining a blood culture to guide appropriate antibiotic therapy. The arrival of the parents is not directly related to the immediate action required before starting antibiotics in this scenario.

5. When printing out an EKG, a nurse notices that the QRS complexes are extremely small. What should be the next step?

A. Alert the physician immediately as this is a sign of impending cardiac arrest.
B. Check to see that all leads are attached and rerun the EKG.
C. Increase the sensitivity control to 20 mm deflection.
D. Decrease the run speed to 50.

Correct answer: C

Rationale: Increasing the sensitivity control to 20 mm deflection will double the sensitivity, allowing for better observation of the small QRS complexes. This step is crucial in obtaining a clearer EKG reading. Choice A is incorrect because small QRS complexes do not necessarily indicate impending cardiac arrest; it's more likely a technical issue. Choice B is not the first step to take when small QRS complexes are observed; it's important to adjust the settings first. Choice D is incorrect because decreasing the run speed to 50 is not the appropriate action for this situation; adjusting the sensitivity control is more relevant to improve the visualization of the complexes.
