1. What effect can medication bound to protein have?

• A. reduced drug availability
• B. limited distribution of the drug to receptor sites
• C. less availability to produce desired medicinal effects
• D. decreased metabolism of the drug by the liver

Correct answer: C

Rationale: Medication bound to protein leads to less availability to produce desired medicinal effects because only unbound drugs can interact with active receptor sites. If a drug is bound to protein, it cannot bind with a receptor site, reducing its effectiveness. Choice A is incorrect because binding to protein reduces drug availability. Choice B is incorrect because distribution to receptor sites is ineffective if the drug is bound to protein. Choice D is incorrect because metabolism does not occur until the drug is removed from the protein molecule by the liver, allowing the protein to return to circulation.

2. What is the most appropriate initial action for a newborn infant with low blood glucose?

• A. Ask the registered nurse to draw another blood sample in 2 hours and repeat the test
• B. Contact the healthcare provider
• C. Contact the registered nurse
• D. Document the results in the newborn's medical record

Correct answer: C

Rationale: The blood glucose level for a newborn infant should remain greater than 40 mg/dL to prevent permanent brain damage. When dealing with low blood glucose in a newborn, the most appropriate initial action is to contact the registered nurse. The nurse will obtain prescriptions regarding feeding the infant with low blood glucose and follow agency policies on feeding infants in such conditions. It is common practice to feed the infant if the glucose level is 40 mg/dL or less. Asking the registered nurse to draw another blood sample in 2 hours and repeating the test is not the most appropriate immediate action, as timely intervention is crucial in this situation. Contacting the healthcare provider may cause unnecessary delays since the registered nurse is usually the first point of contact for immediate actions in this scenario. Documenting the results in the newborn's medical record is essential, but it is not the initial step in managing low blood glucose in a newborn.

3. A nurse assisting with data collection notes that the client exhibits rapid, involuntary oscillating movements of the eyeball when looking at the nurse. The nurse documents this finding using which term?

• A. Ptosis
• B. Nystagmus
• C. Scleral icterus
• D. Exophthalmos

Correct answer: B

Rationale: When a nurse observes rapid, involuntary oscillating movements of the eyeball in a client, this is described as nystagmus. Nystagmus appears as a fine oscillating movement, most notable around the iris. It is important to assess for nystagmus when evaluating ocular muscle weakness. Mild nystagmus at extreme lateral gaze is considered normal; nystagmus in any other position is not. Ptosis refers to a drooping of the eyelid, not rapid eye movements. Scleral icterus is the yellowing of the sclera up to the cornea, indicating jaundice, not related to eye movements. Exophthalmos is a noticeable protrusion of the eyeball, typically seen in hyperthyroidism, not associated with rapid oscillating eye movements.

4. At a health screening clinic, a nurse is educating a young woman about breast self-examination (BSE). The nurse determines that the client demonstrates understanding when she makes which statement?

• A. BSE should be performed monthly after the menstrual period.
• B. BSE is performed after the menstrual period.
• C. Monthly BSE is a recommended method for early detection of breast cancer.
• D. Monthly BSE includes inspection before a mirror and palpation both in the shower and while lying down.

Correct answer: D

Rationale: The correct answer is 'Monthly BSE includes inspection before a mirror and palpation both in the shower and while lying down.' BSE should be performed monthly after the menstrual period, not every other month or on the day menstruation begins. Performing BSE on the seventh day of the menstrual cycle when the breasts are smallest and least congested is recommended. While BSE is a useful tool for early detection, it is not the only method. Regular physical examinations and mammograms are also important. The correct technique for BSE includes inspecting the breasts in front of a mirror, palpating in the shower for easier detection, and conducting palpation while lying down for thorough examination.

5. During data collection of a client with suspected carpal tunnel syndrome, a nurse plans to perform the Phalen test. The nurse should ask the client to perform which activity?

• A. Dorsiflex the foot
• B. Plantarflex the foot
• C. Hold the hands back to back while flexing the wrists 90 degrees for 60 seconds
• D. Hyperextend the fingers with the palmar surfaces of the hands touching, holding the position for 60 seconds

Correct answer: C

Rationale: In the Phalen test, the nurse asks the client to hold the hands back to back while flexing the wrists 90 degrees. This position puts pressure on the median nerve, eliciting symptoms in carpal tunnel syndrome. Dorsiflexing or plantarflexing the foot and hyperextending the fingers are not associated with testing for carpal tunnel syndrome. Acute flexion of the wrist for 60 seconds produces no symptoms in the normal hand.
