• Question 971:

  Which of the following statements describes the purpose of client restraint?

  A. Restraints are a nursing measure used to maintain client control.
  B. Restraints are an emergency intervention taken as a last resort to protect a client from imminent danger.
  C. Restraints are a therapeutic measure designed to positively reinforce client behavior.
  D. Restraints are an emergency measure that can only be taken by a nurse under the direct supervision of a physician.
  B. Restraints are an emergency intervention taken as a last resort to protect a client from imminent danger.

  ---

  The use of restraints as an emergency measure is taken primarily as a last resort to protect a client from harm. Typically, the nurse acts under a physician's order, but in an emergency, the nurse may restrain a client out of necessity for one hour prior to the client being seen by a physician or an advanced practice mental health provider.

• Question 972:

  A diet high in fiber content can help an individual to __________.

  A. lose body weight fast
  B. reduce diabetic ketoacidosis
  C. lower cholesterol
  D. reduce the need for folate
  C. lower cholesterol

• Question 973:

  A client's central venous access device (CVAD) becomes infected.

  Why might the physician order antibiotics to be given through the line rather than through a peripheral IV line?

  A. to prevent infiltration of the peripheral line
  B. to reduce the pain and discomfort associated with antibiotic administration in a small vein
  C. to lessen the chance of an allergic reaction to the antibiotic
  D. to attempt to eliminate microorganisms in the catheter and prevent having to remove it
  D. to attempt to eliminate microorganisms in the catheter and prevent having to remove it

  ---

  Microorganisms that infect CVADs are often coagulase-negative staphylococci, which can be eliminated by antibiotic administration through the catheter. If unsuccessful in eliminating the microorganism, the CVAD must be removed. CVAD use lessens the need for peripheral IV lines and thus the risk of infiltration. In this case, however, the antibiotics are given to eradicate microorganisms from the CVAD. CVAD use has the effect described in Choice "to reduce the pain and discomfort associated with antibiotic administration in a small vein", but in this case, the antibiotics are given through the CVAD to eliminate the infective agent. The route does not prevent an allergic reaction.

• Question 974:

  While the PN is bathing a patient with a chest tube, the tube is accidentally pulled out.

  What is the first priority for the PN?

  A. Attempt to re-insert the chest tube.
  B. Obtain a sterile dressing for the chest tube site.
  C. Discard the contaminated chest tube.
  D. Provide the patient with supplemental oxygen.
  B. Obtain a sterile dressing for the chest tube site.

• Question 975:

  Incidences of child abuse apperar to be higher in the African-American community and might be explained by ___________.

  A. the increased number of African Americans viewing violence on television.
  B. more single-parent households in African-American communities.
  C. stricter child-rearing practices in African-American households.
  D. a higher occurrence of rage in African Americans.
  B. more single-parent households in African-American communities.

  ---

  Child abuse is higher in households with lower socioeconomic status and single parents. The increased incidence might be due to increased stress and fewer support systems.

• Question 976:

  What is the expected date of delivery for the woman who has had their last menstrual period on April 20th?

  A. January 20th
  B. January 27th
  C. January 29th
  D. January 31st
  B. January 27th

• Question 977:

  Select the following fire emergency interventions in correct sequential order.

  

  A. C, B, A, D
  B. A, C, B, D
  C. C, A, B, D
  D. C, A, D, B
  C. C, A, B, D

  ---

  The RACE acronym is used to prioritize and sequence the steps that must be followed when a fire occurs. R stands for rescue patients; A is pulling the fire alarm; C is to contain the fire by closing doors, etc.; and E is extinguishing the fire with a fire extinguisher when possible.

• Question 978:

  A client with a pleural drainage system to suction has gentle bubbling of the water seal. What should the nurse do?

  A. Notify the physician.
  B. Clamp the chest tube.
  C. Replace the system.
  D. Document the finding.
  D. Document the finding.

  ---

  Explanation Explanation/Reference:Gentle bubbling is a normal finding for the client who has a pleural drainage system to suction, so it simply needs to be documented. If the bubbling becomes vigorous, it could indicate a leak, which the nurse needs to investigate. The remaining choices are not necessary.

• Question 979:

  Which type of burn leads to the greatest degree of pain?

  A. A first degree burn
  B. A second degree burn
  C. A third degree burn
  D. A fourth degree burn
  B. A second degree burn

  ---

  Although the first degree burn can cause pain, it is the second degree burn that is the most painful of all. There is a lack of pain with third and fourth degree burns because these burns have destroyed pain sensory nerves.

• Question 980:

  The chemotherapeutic DNA alkylating agents such as nitrogen mustards are effective because they __________.

  A. cross-link DNA strands with covalent bonds between alkyl groups on the drug and guanine bases on DNA
  B. have few, if any, side effects
  C. are used to treat multiple types of cancer
  D. are cell-cycle-specific agents
  A. cross-link DNA strands with covalent bonds between alkyl groups on the drug and guanine bases on DNA

  ---

  Explanation Explanation/Reference:Alkylating agents are highly reactive chemicals that introduce alkyl radicals into biologically active molecules and thereby prevent their proper functioning, replication, and transcription. Choice "have few, if any, side effects" is incorrect because alkylating agents have numerous side effects including alopecia, nausea, vomiting, and myelosuppression. Choice "are used to treat multiple types of cancer" is incorrect because nitrogen mustards have a broad spectrum of activity against chronic lymphocytic leukemia, non-Hodgkin's lymphoma, and breast and ovarian cancer, but they are effective chemotherapeutic agents because of DNA crosslinkage. Choice "are cell-cycle-specific agents" is incorrect because alkylating agents are non-cell-cycle-specific agents.
