,Section A - General Electrical Theory
Q1.
What procedure is essential for obtaining accurate main bearing oil clearance
measurements during an engine rebuild?
A. Measure clearances using a feeler gauge B. Measure clearances using a dial bore
between the bearing and journal gauge on the assembled bearing
C. Measure clearances using a plastigauge D. Measure the bearing shell thickness with
a micrometer and subtract from the housing
bore diameter
Correct: C - Measure clearances using a plastigauge
Rationale:Plastigauge is specifically designed to measure bearing clearances by being
compressed between the journal and bearing, providing a direct and accurate reading. Feeler
gauges are unsuitable for curved surfaces, and indirect methods like subtracting shell
thickness or using a dial bore gauge on the assembled bearing can introduce errors due to
bearing crush and deformation.
Q2.
A client reports worsening nasal congestion despite using oxymetazoline (Afrin) nasal
spray every 2 hours. What is the nurse's best response?
A. Switch to a different over-the-counter B. Use a saline nasal spray to moisturize the
decongestant to avoid tolerance. nasal passages and reduce congestion.
C. Increase the frequency of the nasal spray D. Overuse of nasal decongestants results
to every hour to achieve better relief. in rebound congestion.
Correct: D - Overuse of nasal decongestants results in rebound congestion.
Rationale:Oxymetazoline (Afrin) is an effective nasal decongestant, but overuse results in
worsening or "rebound" congestion. It should not be used more than every 4 hours. To avoid
future rebound congestion with nasal sprays, it is recommended that they be used for no
more than 3 to 5 days.
Q3.
A home health nurse is planning the order of daily visits. Which client should the nurse
visit first?
A. A client with a chronic wound requiring a B. A client with hypertension who requires a
dressing change blood pressure check

, Section A - General Electrical Theory
C. A client with laryngeal cancer who has D. A client with diabetes who needs insulin
undergone a laryngectomy administration
Correct: C - A client with laryngeal cancer who has undergone a laryngectomy
Rationale:The client with laryngeal cancer has a potential airway alteration and should be
seen first.
Q4.
The nurse arriving for the shift is preparing to perform an initial assessment of a sedated,
mechanically ventilated client. Which actions should the nurse prioritize? Select all that
apply.
A. Perform a comprehensive neurological B. Administer the prescribed sedative
examination. medication.
C. Ask visitors to leave. D. Obtain a detailed medical history from the
family.
Correct: C - Ask visitors to leave.
Rationale:The first priority when caring for the critically ill client is to assess airway and
breathing. Alarm settings should be confirmed each shift, more frequently if necessary.
Ensuring that the client cannot speak ensures that air is going through the endotracheal tube
and not around it. Auscultating for equal bilateral breath sounds assists in confirming that the
tube is above the carina.
Q5.
In addition to its primary function, Network Address Translation (NAT) can be utilized to
restrict which clients are permitted to access a server. Which of the following mechanisms
is used for this purpose?
A. VPN B. ACL
C. DHCP D. VLAN
Correct: B - ACL
Rationale:NAT can be combined with Access Control Lists (ACLs) to restrict which external
hosts can access internal servers. ACLs filter traffic based on source IP, destination IP, and
port, providing a security layer beyond basic NAT translation.
Q6.
Which procedure must be performed before replacing a common rail fuel injector?
A. Disconnect the battery and drain the B. Depressurize the fuel tank by removing
engine oil. the fuel cap.
