B. I should take this medication when my spasms are bad.
C. My muscle strength should improve a lot in 2 to 3 days
D. I need to apply a sunscreen when I go outside - correct answerCorrect Answer : D

A nurse is preparing to administer cephalexin oral suspension to an older adult client
who has difficulty swallowing pills. Which of the following actions should the nurse take?
A. Store the medication at room temperature
B. Avoid shaking the medication before administration
C. Check the client for a penicillin allergy
D. Monitor the client for constipation - correct answerCorrect Answer : C
Cephalexin is a cephalosporin antibiotic, and there is a potential for cross-sensitivity in
clients who are allergic to penicillin. Up to 10% of people with a penicillin allergy may
also be allergic to cephalosporins. Checking for a penicillin allergy helps prevent an
adverse reaction, making it a critical safety measure before administering cephalexin.
A nurse manager is providing an educational program on antibiotic sensitivity to
bacterial infection. The nurse should include in the teaching that vancomycin is
Indicated for which of the following infections?
A. Pseudomonas aeruginosa
B. Klebsiella
C. Methicillin resistant staphylococcus succus
D. candida - correct answerCorrect Answer : C
Vancomycin is a glycopeptide antibiotic that is effective against gram-positive bacteria,
particularly against MRSA, which is resistant to other antibiotics like methicillin. It is not
effective against gram-negative bacteria such as Pseudomonas aeruginosa and
Klebsiella. Candida is a fungal infection and is not treated with vancomycin. Therefore,
in this educational program, the nurse manager should emphasize that vancomycin is
indicated for the treatment of infections caused by MRSA.
A nurse In a community health clinic is administering seasonal inactive influenza
vaccine. Beforeadministering it, the nurse must confirm that the client is not allergic to
which of the following:
, A. Eggs
B. Yeast
C. Gelatin
D. Shellfish - correct answerCorrect Answer : A
Influenza vaccine production involves growing the virus in eggs. Therefore, the vaccine
may contain trace amounts of egg proteins. Some individuals may be allergic to egg
proteins and may experience an allergic reaction after receiving the vaccine. For this
reason, healthcare providers should always ask their patients about egg allergies before
administering the influenza vaccine.
Yeast, gelatin, and shellfish are not typically present in the seasonal inactive influenza
vaccine, so allergy to these substances is not a concern when administering the
vaccine. However, if a person has a known allergy to any of the ingredients in the
vaccine, they should inform their healthcare provider before receiving it.
A nurse is reviewing the medical record of a client who is to receive the first dose of
cefoxitin, a cephalosporin via intermitent IV bolus Which of the following findings should
the nurse Identify as a contraindication for the client to receive cefoxitin and report to
the provider?
A. A recent history of diarrhea for 3 days.
B. Serum creatinine 0.8 mg/dL.
C. Severe allergy to amoxicillin.
D. A history of phlebitis following an IV infusion of 0.9% sodium chloride with 10 mEq
potassium chloride. - correct answerCorrect Answer : C
Cefoxitin is a cephalosporin antibiotic and can cause allergic reactions in people who
are allergic to penicillin or other beta-lactam antibiotics like amoxicillin. Therefore, a
severe allergy to amoxicillin is a contraindication for the client to receive cefoxitin, and
the nurse should report this finding to the provider immediately.
A nurse is reviewing guidelines for prophylactic antibiotics. The nurse should Identify
that prophylactic antibiotic therapy is not recommended for which of the following
clients?
A. A client who bn a fever of unknown origin
B. A client who has a prosthetic heart valve is having dental surgery
C. A client who had an emergency cesarean section
D. A client following total hip arthroplasty. - correct answerCorrect Answer : A
Option a, on the other hand, does not warrant prophylactic antibiotics. A fever of
unknown origin does not necessarily indicate an infection, and antibiotics should only be
given when there is a confirmed bacterial infection. Inappropriate use of antibiotics can
lead to antibiotic resistance and other adverse effects
A nurse is providing teaching to a client who has a skin infection and a new prescription
for gentamicin topical cream. Which of the following instructions should the nurse
provide?
A. Wash the affected area with soap and water before applying cream.
B. Apply a heavy layer of cream well beyond the border of the affected site.
