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. Which of the following solutions is routinely used to flush an IV device before and after the administration of blood to a client?

• A. 0.9% sodium chloride
• B. 5% dextrose in water solution
• C. Sterile water
• D. Heparin sodium

Correct answer: A

Rationale: The correct answer is 0.9% sodium chloride. Normal saline is 0.9% sodium chloride, which has the same osmolarity as blood and does not cause cell lysis. Choices 2 and 3, 5% dextrose in water solution and sterile water, are hypotonic solutions that can lead to cell lysis. Choice 4, heparin sodium, is an anticoagulant and is not used for flushing IV devices before and after blood administration.

3. Mr. H. is upset about being in the hospital for another day because he states it costs too much. The rights he is likely to demand include all of the following except:

• A. the right to examine and question the bill
• B. the right to reasonable response to requests
• C. the right to refuse treatment
• D. the right to confidentiality

Correct answer: D

Rationale: Confidentiality is the maintenance of privacy of information, which is not directly related to the issue Mr. H. is facing. The question indicates that Mr. H. is concerned about the cost of staying in the hospital, which pertains more to financial aspects and the right to examine and question the bill. The right to a reasonable response to requests and the right to refuse treatment are also crucial patient rights that Mr. H. may demand in his current situation. Therefore, the correct answer is the right to confidentiality, as it is not specifically relevant to the scenario presented.

4. A client with an ileus is placed on intestinal tube suction. Which of the following electrolytes is lost with intestinal suction?

• A. calcium
• B. magnesium
• C. potassium
• D. sodium chloride

Correct answer: D

Rationale: The correct answer is sodium chloride. Duodenal intestinal fluid is rich in potassium (K+), sodium (Na+), and bicarbonate. When suctioning is used to remove excess fluids due to ileus, it results in the loss of sodium chloride (NaCl) leading to decreased sodium (Na+) levels. Choices A, B, and C are incorrect because calcium, magnesium, and potassium are not typically lost in significant amounts through intestinal tube suction in the context of treating ileus.

5. A nurse calculates a newborn infant's Apgar score 1 minute after birth and determines that the score is 6. What is the most appropriate action for the nurse to take?

• A. Initiate cardiopulmonary resuscitation
• B. Gently stimulate the infant by rubbing his back while administering oxygen
• C. Recheck the score in 5 minutes
• D. Provide no action except to support the infant's spontaneous efforts

Correct answer: B

Rationale: The Apgar score is a method for rapidly evaluating an infant's cardiorespiratory adaptation after birth. The nurse assigns scores in five areas: heart rate, respiratory effort, muscle tone, reflex response, and color, totaling the scores. A score of 8 to 10 requires no action other than supporting the infant's spontaneous efforts and observation. A score of 4 to 7 indicates the need to gently stimulate the infant by rubbing his back while administering oxygen. If the score is 1 to 3, the infant requires resuscitation. Therefore, in this scenario with an Apgar score of 6, the correct action is to gently stimulate the infant by rubbing his back while administering oxygen. Initiating cardiopulmonary resuscitation would be excessive at this point, and rechecking the score in 5 minutes may delay necessary interventions. Providing no action except to support the infant's spontaneous efforts is insufficient for a score of 6, indicating the need for stimulation and oxygen administration.
